ICQ
Send completed observations via e-mail to: icqcsc@eps.harvard.edu
PLEASE NOTE that "tab"s should NOT be used anywhere in the tabulated data in place of spaces; use only the space-bar for spaces.
In order to warrant publication in the ICQ, contributors must include all of the following data for each tabulated observation: (1) full UT date, to 0.01 day; (2) total visual magnitude estimate to 0.1 mag; (3) magnitude method used to make the estimate; (4) acceptable source or reference from which the V or visual magnitudes of comparison stars were taken (photographic comparison magnitudes or magnitudes of deep-sky objects are not acceptable, for example); (5) and full instrumenation details (aperture in centimeters, type of instrument, f/-ratio, and magnification (for visual observations, or seconds of exposure for CCD observations). The ICQ Keys to Abbreviations, used in the formatting that is described below, are available on-line.
It is necessary to format data in the manner described below so that the data can be published/archived and so that errors are not introduced in the transmission of data from observer to archive; the full manner is simply given here for convenience, and in the hope that contributors will attempt to save the ICQ staff time (and possible errors) in converting their data to the proper format. If you do not use the formal format described below, please provide all of the necessary data in an easy-to-ready tabular format of your own choosing (with no tabs, please), and be sure to check and double-check all data before sending! A new format extending beyond column 80 *for CCD observations only* was introduced at the beginning of 2002; this was explained in the October 2001 issue of the ICQ and is detailed below.
**** NOTE: Do *NOT* repeat any of the sample/test line given immediately
below in your actual reported data (other than perhaps the letters
"ICQ" in columns 69-71)!!!! The characters and symbols in each column
on the line below are meant only as *GUIDES* to help you fill out
each line properly! ****

The above 80-column format is that which we use in machine-readable form
for the ICQ observations; this new format was established in 1995 to
accomodate the new designation scheme for comets. NOTE: Columns were
added beyond column 80, beginning 2002 January 1, to add additional information
for CCD photometry of comets.
The first 10 columns are for the comet's identification. The first
three columns are blank for long-period comets. For one-apparition short-period
comets, columns 1 and 2 are blank, and column 3 contains a capitalized "P".
In both of these cases (long-period comets and one-apparition short-period
comets), the year-and-halfmonth designation goes in columns 4-9 (columns 4-7
contain the year; column 8 contains the capitalized halfmonth letter; and
column 9 contains the halfmonth numeral). Column 11 contains a lower-case
letter denoting nuclear components if such exist (even though such letters
are usually given in text form as upper-case letters), and this column is so
used for all such split comets; in the case of the rare numbered split comets
(such as 73P) where more than 26 components were discovered (thus, the
components went from "Z" to "AA"), the two letters should go in columns 10
and 11 (if we ever get to the situation where a comet with a year/letter
designation spilling over into column 10 has more than 26 components, we
will address the problem at that time). Columns 1-3 are used for "numbered"
short-period comets (those seen at two or more returns to perihelion); this
number is to be given "flush right" (i.e., " 1" for 1P/Halley, " 47" for
47P/Ashbrook-Jackson, and "116" for 116P/Wild 4). There were 178 such
numbered comets as of Oct. 2006. All comet designations can be found in the
CATALOGUE OF COMETARY ORBITS (1995 editions onwards) published by the
Smithsonian Astrophysical Observatory, and recent designations are published
in the pages of the ICQ.

*Short-period comet code for numbered, multi-apparition periodic comets;
cols 1-3 left blank in case of long-period comets; place a capitalized "P"
in column 3 (with columns 1 and 2 blank) for 1-apparition short-period comets.
**Halfmonth designation (capitalized halfmonth letter in column 8;
numeral in column 9; split-nucleus capitalized letter in column 10);
columns 10 and 11 may also be used for minor-planet-designated comets,
where letters are given in columns 8 and 9, and 10 and 11 are reserved
for digits (to 99, flush LEFT, meaning single digits go in column 10
with no leading zero) -- for minor-planet-designated comets with post-letter
digits exceeding 99, use column 10 for letters A, B, C, D, etc., to
indicate 100, 110, 120, 130, etc., with column 11 holding the ones digit.

For example, here are some recent comets, with their corresponding designations

123456789012
Then YYYY, MM, and DD.DD are the year, month, and date (to 0.01 day)
of the observation in UT. NOTE: leading zeroes should only be put in the
month and date data; none of the other fields on the 80-character record
should have leading zeroes.
e (column 26) is for extinction notes and other notes, using the
ICQ abbreviations.
M (column 27) is the magnitude method used for the magnitude estimate
[B = simple Out-Out or VBM (Van Biesbroeck-Bobrovnikoff-Meisel) method; E =
Extrafocal-Extinction (Beyer) method; I = in-focus; M = Modified-Out
(Morris) method; S = In-Out or VSS (Vsekhsvyatskii-Steavenson-Sidgwick) method].
mm.m: (columns 28-33, decimal point in column 31) is the total visual
magnitude estimate (we do not want estimates of the nuclear condensation
alone), given to 0.1 magnitude. Column 28 is the column for a left
bracket ([), which represents the comet was not seen and was fainter than a
given magnitude. If the magnitude estimate is not very accurate, or made
under poor conditions, then a colon (:) is placed immediately after the
magnitude (for example, 11.3:).
r (columns 34-35) is the reference or source of comparison stars used
for making the magnitude estimate (if more than one source was used, the
primary source only must be listed here); here we use a 2-letter code (or 1-
letter code in column 34 only).

AAA.ATF/xxxx are the specifications concerning the instrument used for
the observation. NOTE: If the magnitude estimate is made with one telescope
and the tail-length estimate is made with a second telescope, two different
lines must be entered! AAA.A (columns 36-40) is the instrument aperture
in centimeters, given to 0.1 cm. An important thing for the recorder to
remember is only to use significant figures (example: if the observer reports
his telescope aperture as 20 cm, the recorder should not put 20.0 cm, but 20
cm). T (column 41) is the instrument type, as coded by the 1-letter key.
F/ (columns 42-43) is the focal ratio (f/-ratio) of the instrument, and
xxxx (columns 44-47) is the power (magnification) used in the case of visual
observations or the duration of the CCD or photographic exposure in seconds.
Both of these values should be entered FLUSH RIGHT (that is, ones digits go
in the right-most column, tens digits in the second column from right, etc.);
if a CCD exposure in which the duration is given in seconds, a lower-case
letter "a" must be placed in column 44 if the exposure length is less than
1000 seconds; if the exposure duration is 1000 seconds (= 16m40s) or longer
(but less than 2000 seconds = 33m20s), an upper-case "A" must be placed in
column 44; an upper-case "B" in column 44 indicates an exposure time of
2000-2999 sec (note that the thousands digit is replaced by these letters
A, B, C, etc.). The f/-ratio must be rounded (even) to the nearest integer;
thus, f/4.5 becomes " 4" and f/3.5 also become " 4". There is no way to
include a decimal part of an f/-ratio in this tabulation; decimals must be
rounded.
&dd.dd (columns 49-54) is the observer's estimate of the comet's coma
diameter in arc minutes at the time of observation. The less-than sign
for column 49 indicates the column used for an ampersand (&), which indicates
an approximate measurement, or a less-than or greater-than sign. The
diameter may be given to 0.01 arcmin, but again only significant figures
should be entered (example: when the comet was large, > 10', measurements
would probably never even be given to 0'.1, because it would be very difficult
to get so exact an estimate when the coma is so large). Do NOT give the coma
to 0.1 arcmin if the uncertainty is ± 1 arcmin! (In other words, if you
estimate a coma diameter of 8' ± 2', do not give it as "8.0"! Only give it
as "8.0" if the uncertainty is ± 0'.3 or better.) CCD photometrists should
give here the APERTURE SIZE of the software applied to the comet's coma to
yield the tabulated magnitude, with a plus sign (+) in column 49; any larger
measured coma diameter than that used for the magnitude should then be
given in the descriptive information (or after 2002 January 1, in the
tabulated data beyond column 80).
n (column 55) is for a special note describing the physical appearance
of the central condensation, described in the July 1995 issue of the ICQ,
page 92 (d = faint disk within the coma, D = bright disk within the coma,
s = faint "stellar or nearly-stellar condensation, etc.).
DC (columns 56-57) is the degree of condensation of the comet as
estimated by the observer (on a scale of 0 to 9, where 0 is completely diffuse
and 9 is completely stellar in appearance). The digit goes in column 56. If
an observer estimates DC = 5-6, then a slash (/) goes in column 57 following
a "5" (thus: 5/ ). A "5/" means EITHER 5.5 OR 5 to 6; there is no way to
denote an approximate DC estimate in this tabulation.

&t.ttm (columns 59-64) is the tail length in degrees (to 0.01 degree of
arc), with the less-than sign in column 59 indicating the same as column 49
for the coma diameter (see above). Column 59 can be used for either a note
or for a second digit if the tail length is 10 degrees or longer. For tail
lengths in degrees, a decimal always goes in column 61 and the value can
extend to column 63. For tail lengths in minutes or seconds of arc, the
lower-case letter "m" or "s" (respectively) is placed in column 64 and the
value is given to 0.1 with a decimal point in column 62 instead of 61.
Do NOT give the tail to 0.1 unit if the uncertainty is ± 1 unit! (In
other words, if you estimate a tail length of 30' ± 3', do not give it
as "30.0"!)
ANG (columns 65-67) is the position angle at which the center of the
tail is directed (0 = north, 90 = east, 180 = south, 270 = west, etc.).
This number is entered flush right *in integer form only* (round even), so
that if the p.a. is 56 degrees, a blank is entered in column 65 and "56" is
entered in columns 66 and 67. There is no way to denote an approximate p.a.
in this tabulation.
RRRRRR (columns 69-74) is the reference for publication (which gets
changed upon publication). You should enter ICQ XX here.

* (column 75) is the column for a revised observation (use an asterisk
here) if the observation replaces one given previously).
OBSxx (columns 76-80) is a 3-letter, 2-digit code to indicate who the
observer is. Columns 76-78 give the first 3 letters of the observers last
name (family name), and the digits are simply added in where there are more
than one observer with the same first 3 letters in his last name. If you
do not know the 2-digit appendage to the first 3 letters of your last name,
put "xx" after the letters, and the appropriate numbers will be assigned by
the ICQ staff.
ONLY GIVE FIGURES TO PROPER SIGNIFICANCE. (i.e., do not give tail to 0.01
degree if it is only known to the nearest 1 degree or 0.1 degree!! etc.)
Note that descriptive information (that is, textual information that does not fit the above-described tabulated format) should be given separately, listed in chronological order by comet, with UT date and time given to 0.01 day. At the discretion of the ICQ staff, this material will be published in the separate "Descriptive Information" section in the ICQ. Follow the examples for descriptive information as published in the ICQ (a sample page is posted on this Website on the ICQ "front page").
Other specific examples of the ICQ observation format are provided below:
EXAMPLES OF OBSERVATIONS IN CORRECT ICQ FORMAT.
Examples are given below for both CCD and visual observations.
Please read all instructions carefully, and then observe the real data
below to remove any questions. For each set, unnumbered comets with
orbital periods > 30 yr are given first (these have no characters in
columns 1-3), followed by numbered comets and by unnumbered comets
with periods < 30 yr (which both have designation numbers or letters
in columns 1-3). Note that, prior to each set of observations below,
two 80-character lines are provided for reference -- the first being
a simple column count by tens, and the second being a standard
template for the observation columns.

************************************
Beginning 2002 Jan. 1, the observation record was extended beyond
column 80 for CCD observations only (see Oct. 2001 and Jan. 2002 ICQ).
New ICQ format for tabulated data to include more CCD information,
starting in column 81:

columns 81-82, f: if comparison stars are in the same frame as the comet,
write "I" in column 81; if comparison stars are in the next field (one
instrumental field size outside that of the comet), write "N" in column 81;
otherwise, put a two-digit number in columns 81-82 (flush right) indicating
the estimated distance of comparison-star field from the comet in whole
degrees (with 99 indicating 99 deg or greater; 00 indicates less than 1 deg);
write "MA" in columns 81-82 if multiple reference stars are used at multiple
air masses around the sky
columns 83-86, InT: integration time of comparison-star field when
the field is outside that of (or different from) the comet exposure
(given in seconds, flush right); use identical column format to that used
for CCD exposure of comet field in columns 44-47; if multiple fields are
used with different exposure times, write down that exposure time that
was the longest used for the photometric reduction; this means that
a lower-case "a" in column 83 indicates an exposure time under 1000 seconds,
an upper-case "A" indicates an exposure time of 1000-1999 seconds (with the
thousands digit replaced by the "A"), an upper-case "B" indicates an
exposure time of 2000-2999 seconds (with the thousands digit replaced by
the "B"), etc.
columns 87-93, APERTUR: columns 88-92 hold numerical dimension of
photometric-aperture size, with decimal in column 90; column 93 has
letter to denote units (d = degrees, m = arcmin, s = arcsec); column
87 gives the shape of the photometric aperture (S = square, C = circular).
NOTE that this means that only actual, measured coma diameters will
appear in columns 50-54 --- and that the plus-sign (+), which indicated
an aperture size for electronic photometry, will no longer be used in
column 49.
columns 94-100, camchip: three-character key to specify CCD camera in
columns 94-96 (e.g., MCV = Mutoh CV-16II camera); then three-character
key to specify camera's CCD chip in columns 98-100 (e.g., T25 = TC255;
K16 = KAF-1600); column 97 contains "a" to denote an anti-blooming CCD
columns 102-104, SFW: 3-character key to denote the software package used
to derive the magnitudes (e.g., G70 = Guide 7.0; FPr = FitsPro). This
is different from the source of comparison-star magnitudes.
column 106, C:
0 = no correction
1 = correction for bias (bias subtracted)
2 = flat-field corrected (flat-fielded)
3 = 1 + 2
4 = dark-subtracted (and bias-subtracted)
5 = 2 + 4
columns 108-109, ##: number of CCD frames taken of comet on same night,
for verification of proper identification (flush right); if accurate
astrometry was performed and submitted formally to the ICQ/MPC/CBAT
for publication, place a "P" for published in column 108 or a "U"
in column 108 for either "unpublished" or "publication status unknown"
(and, if more than 9 images were obtained on a single night of this
comet and astrometry was also reported, simply put a "9" in column
109 in addition to the letter in column 108)
If a number of co-added frames were used for the photometry,
then this number should be given in columns 108-109, and place
an asterisk (*) in column 110 to denote this fact.
columns 111-114, u.uu: estimated error/uncertainty in magnitude
(decimal point in column 112)
columns 116-119, xx.x: magnitude of the comparison star closest in
brightness to that of the comet
columns 121-129, PIXELSIZE: assumed rectangular shape,
with one pixel side given numerically in columns 121-124 (decimal
point in column 123) and the other (perpendicular) side given
numerically in columns 126-129 (decimal point in column 128);
column 125 contains the letter that denotes the units
(d = degrees, m = arcmin, s = arcsec)
