Description:
The catalog is a complete summary of all observations of CO isotopes
in galaxies up to spring 1984. It consists of seven tables. Refs.dat
describes the reference for CO observations of galaxies. Telescop.dat
describes the properties of the telescopes used for observations.
Detect.dat and uprlmits.dat contain a compilation of data on galaxies
that have been observed in CO. Most of the characteristics listed here
are observed properties. The detected galaxies are listed first,
followed by galaxies with upper limits. Upper limits are given for
detected galaxies if the detection is disputed or if the limits refer
to transitions or regions that have not yet been detected. Temp.dat is
a comparison of the antenna temperature scales used in the references
in this catalog. Maps.dat lists the coverage, resolution, observed
structure of CO maps of galaxies, and notes.dat contains notes to
tables.

Note on Galaxy:
Galaxies with NGC numbers are listed first, followed by IC, DDO, Mk,
and named galaxies. Alternate names are given if they are one of the
above, or a Messier number.
Note on RMType:
Revised morphological type from the Second Reference Catalogue of
Bright Galaxies (de Vaucouleurs, de Vaucouleurs, and Corwin 1976; RC2;
Cat. VII/112).
Note on MType:
Morphological type from the Revised Shapley-Ames Catalog (Sandage and
Tammann 1981; RSA; Cat. VII/51).
Note on MaxisD:
The apparent major axis diameter of the galaxy, measured at the 25 mag
sq. arcsec surface brightness isophote. The diameters are from the RC2
in units of minutes of arc.
Note on Bmag:
The apparent blue magnitude of the galaxy in the B(T) system of RC2.
The numbers quoted were taken from the RSA, and have been corrected
for galactic and internal absorption. The absorption corrections are
described in the RSA. Since blue magnitudes were not available for the
DDO galaxies, apparent photographic magnitudes from the Fisher and
Tully (1975A&A....44..151F 1975A&A....44..151F) survey of the DDO list are given for these
objects. These magnitudes are not corrected for galactic or internal
absorption.
Note on RV:
Radial velocity, in units of km/sec of the galaxy relative to the
center of the Local Group. The velocities are taken from the
unpublished Catalog of Galaxy Redshifts (Rood 1980, Cat. VII/36).
Note on Cflag:
For one galaxy (IC 4553), this field will contain an N, meaning the
radial velocity is for the northern component, or an S for the
southern component.
Note on HIflux:
Total H I flux of the galaxy, in units of Jy*km/sec. The fluxes are
taken from the unpublished General Catalogue of 21 Centimeter Line
Data (Bottinelli, Gouguenheim, and Paturel 1983; BGP -- see Cat.
VII/238). The BGP does not include DDO galaxies, so H I fluxes are
taken from the Fisher and Tully (1975A&A....44..151F 1975A&A....44..151F) survey of the
DDO catalog.
Note on VelWidth:
The full velocity width of the H I profile, defined so that 50% of the
profile area falls within this width. For the BGP galaxies, these
widths were all remeasured on the original profiles and therefore
constitute a homogeneous sample.
Note on Sampling:
The sampling of the CO observations, defined as the fraction of the
optical galaxy that was surveyed. The sampling is given as the product
of the resolution of the observations times the number of positions in
the galaxy that were examined - the resolution being the fraction of
the optical galaxy covered by a single telescope beam.
Note on Mflag:
If the character M appears in this byte, the galaxy has been mapped
and the other parts of the sampling field will be blank.
Note on TA:
Peak antenna temperature of the detected galaxy. The format of the
field is as follows.
Note on f_TA:
< = upper limit
? = marginal detection
N = not available
P = in preparation
Note on COcode:
blank : J=1-0 transition of 12CO (115.2712GHz)
(2-1) : J=2-1 transition of 12CO (230.5380GHz)
(13) : J=1-0 transition of 13CO (110.2014GHz)
(18) : J=1-0 transition of C18O (109.7822GHz)
Note on f_TotEmis:
Character N, for not available, if the published detection was
presented only as an antenna temperature.
Note on TotEmis:
The total observed integrated emission ... for detected galaxies. For
most mapped galaxies the total emission is not published and cannot
easily be deduced from the data in the literature. Hence, this field
primarily lists the integrated emission of galaxies detected at a
single point ... that can be inferred from the features field of
refs.dat above.
Note on COflux:
The extrapolated total CO flux that represents the entire emission of
a detected galaxy. See Verter (1985ApJS...57..261V 1985ApJS...57..261V) for a discussion
of how these values were obtained.

Note on Ref:
See References (refs.dat). When several lines are required, the
Reference code is repeated.
Note on Sig:
The significance level of the upper limits given in the reference,
defined as the factor by which the rms noise temperature of the
reported null detections has been multiplied ... Upper limits at the
same significance level may still represent different sensitivities if
the data differ in velocity resolution. If this byte is blank, the
reference did not have any upper limits.
Note on u_Sig:
If this byte contains a question mark, the significance level was not
given in the reference.
Note on TempS:
The symbol which was used in the reference for the final temperature
scale. Different authors have used different approaches to obtain
temperatures labeled T(A)
Note on Correc:
Antenna efficiency corrections described in the reference.
Note on note:
A UH in this field indicates that the reference claims to have
employed the chopper wheel calibration technique described in Ulrich
and Haas (1976ApJS...30..247U 1976ApJS...30..247U).

Note on Galaxy:
If this field is blank, the resolution, number of map points, shape of
points, and reference fields are continuations of the previous record.
Note on Dtype:
The structure of the observed CO distribution, according to the
classification scheme of Morris and Rickard (1982). In this scheme,
the distribution types are distinguished by the strength of the
central source and the degree of continuity of the disk emission, as
follows:
1 = central source + disk
2 = central source + annulus
3 = annulus without central source
4 = emission from isolated regions
5 = no detectable emission (not used in this file)
Note on Res:
The resolution of the observations, defined in the sampling field of
detections.dat as the FWHM area of the antenna beam divided by the
area inside the 25 mag/sq arcsec. surface brightness isophote of the
galaxy. The isophotal areas were calculated using the diameters given
in RC2 and the inclination angle ... As defined, the colloquial
expression high resolution corresponds to low numbers in this field.
Note on Spts:
Describes the location and grouping of the observed positions. A line
is a string of points that goes through the center of the galaxy, and
is often aligned with the major axis (MA) or minor axis (mA).
A cross is two lines at roughly right angles, whereas a strip is a
line that does not pass through the center. When many positions at
more or less even spacings are observed, the map points are a grid.

Remarks and Modifications:
The original ADC documentation by Lee E. Brotzman was used to create
this ReadMe file.
The Catalog of CO Observations of Galaxies was sent to the
Astronomical Data Center (ADC), NASA Goddard Space Flight Center,
by the Centre de Donnees Stellaires (CDS) in January 1985.
This version was in the form of a typesetting input tape as used to
produce the published paper.
The original tape contained six files: a file with the text of the
published paper and one file for each of the tables in the paper. The
table files contained column headings, spacing control information,
and the notes.
ADC personnel made a separate file for the notes, removed all column
headings and blank records, and reduced each column to a common
format. A FORTRAN program was run that checked the validity of each
field according to its data type and value. The only file not included
in the version of the VCO distributed by the ADC is the file
containing the text of the published paper.
* 04-Aug-2004: Files were slightly reformatted at CDS to express
floating-point number in a standard form, e.g. original flux coded
with parenthesized exponent like 4.4(1) were converted into 4.4E+1.
