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.

Code Code name Character string that represents the reference in the following files. If this field is blank, the reference, description, telescope, and features: fields are continuations of the previous record. --- Ref Reference --- Desc Brief description of the paper --- Telesco Telescope Standard abbreviation for the telescope that made the observations; see Telescopes (telescop.dat). --- Feature Features Describes the features observed. The following abbreviations were used: nuc - galaxy nuclei dust - patches of obscuration H II - H II regions OB - OB associations M - there is a map A map is defined as three or more detected positions per galaxy; see CO Maps of Galaxies (maps.dat). --- Telesco Telescope Standard abbreviation for the observing facility. --- Diam Diameter m FWHM Beam FWHM Full width at half maximum in minutes of arc. arcmin Freq Frequency Observing frequency of beam FWHM in GHz. GHz Ref Reference Literature reference for equipment and performance of the telescope. This can either be a code name (see refs.dat, or a complete reference. --- ID Galaxy name 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. --- RMType Revised morphological type Revised morphological type from the Second Reference Catalogue of Bright Galaxies (de Vaucouleurs, de Vaucouleurs, and Corwin 1976; RC2). --- MType Morphological type Morphological type from the Revised Shapley-Ames Catalog (Sandage and Tammann 1981; RSA). --- MaxisD Major axis diameter 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. arcmin Nflag1 Note flag Lowercase letter that corresponds to the note flag described in Notes to CO Observations (notes.dat). All of the note flag fields appearing below are defined similarly. --- BlueMag Apparent blue magnitude 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 (1975) survey of the DDO list are given for these objects. These magnitudes are not corrected for galactic or internal absorption. mag Nflag2 Note flag --- RV Radial velocity 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), which is available on magnetic tape from the ADC. km/s Nflag3 Note flag --- Cflag Component flag 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. --- HIflux H I flux 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). The BGP does not include DDO galaxies, so H I fluxes are taken from the Fisher and Tully (1975) survey of the DDO catalog. The format of the field is as follows: Mantissa bytes 66-69, format F4.1 Left parenthesis byte 70, format A1 or 1X Exponent byte 71, format I1 Right parenthesis byte 72, format A1 or 1X Note flag byte 73, format A1 Jy/km/s LeftP1 Left parenthesis --- Exp1 Exponent --- RightP1 Right parenthesis --- Nflag4 Note flag --- VelWidth H I FWHM 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. --- Nflag5 Note flag --- Mflag Mapping flag If the character M appears in this byte, the galaxy has been mapped and the other parts of the sampling field will be blank. --- Sampling 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. Note on Resolution - the fraction of the optical galaxy covered by a single telescope beam. --- LeftP2 Left parenthesis --- Exp2 Exponent --- RightP2 Right parenthesis --- ObsNum Number of observations --- TempCom Temperature comment character < - upper limit ? - marginal detection N - not available P - in preparation --- AntTemp Peak antenna temperature Peak antenna temperature of the detected galaxy. The format of the field is as follows. --- COcode CO transition code blank - J=1-0 transition of 12CO (2-1) - J=2-1 transition of 12CO (13) - J=1-0 transition of 13CO (18) - J=1-0 transition of C18O --- EmisCom Emission comment character Character N, for not available, if the published detection was presented only as an antenna temperature. --- TotEmis Total observed emission 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. K/km/s COflux Extrapolated net CO flux The extrapolated total CO flux that represents the entire emission of a detected galaxy. See Verter (1985) for a discussion of how these values were obtained. Jy/km/s LeftP3 Left parenthesis --- Exp3 Exponent --- RightP3 Right parenthesis --- Ref Reference code, see Reference (refs.dat) --- ID Galaxy name --- MType Morphological type --- MaxisD Major axis diameter arcmin Nflag1 Note flag --- BlueMag Blue magnitude mag Nflag2 Note flag --- RV Radial velocity km/s Nfalg3 Note flag --- Cflag Component flag --- HIflux H I flux Jy/km/s LeftP1 Left parenthesis --- Exp1 Exponent --- RightP1 Right parenthesis --- Nflag4 Note flag --- VelWidth H I FWHM --- Nflag5 Note flag --- Sampling Sampling --- LeftP2 Left parenthesis --- Exp2 Exponent --- RightP2 Right parenthesis --- ObsNum Number of observations --- TempCom Temperature comment character --- NAntTemp Noise antenna temperature Noise antenna temperature of a galaxy with upper limits. When a reference contained upper limits for several points in a galaxy, the average is shown. The significance level of the upper limits, defined as the factor by which the rms noise temperature of the reported null detections has been multiplied, is listed for each reference in temperatures.dat The format of the field is as follows: Note on Comment char < - upper limit N - not available P - in preparation --- Ref Reference code --- Ref Reference code See References (refs.dat). If this field is blank, the corrections and comments fields are continuations of the previous record. --- Telesco Telescopes. See telescop.dat --- Siglevel Significance of upper limits 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. --- Avaflag Availability flag If this byte contains a question mark, the significance level was not given in the reference. --- Nflag Note flag Lowercase letter that corresponds to the note flag described in Notes to CO Observations (notes.dat). --- TempS Temperature symbol 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) --- Correc Corrections Antenna efficiency corrections described in the reference. --- note Comments A UH in this field indicates that the reference claims to have employed the chopper wheel calibration technique described in Ulrich and Haas (1976). --- ID Galaxy name If this field is blank, the resolution, number of map points, shape of points, and reference fields are continuations of the previous record. --- Dtype Distribution type 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) --- Nflag1 Note flag Lowercase letter that corresponds to the note flag described in Notes to CO Observations (notes.dat). All of the note flag fields appearing below are defined similarly. --- IncAng Inclination angle deg Nflag2 Note flag --- Res Resolution 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. --- LeftP Left parenthesis --- Exp Exponent --- RightP Right parenthesis --- Nflag3 Note flag --- NumMap Number of map positions observed --- Spts Shape of points 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. --- Ref Reference See References (refs.dat). --- Fflag File flag D if the note is from detect.dat or uprlmits.dat; T if the note is from temp.dat; or M if the note is from CO Maps of Galaxies (maps.dat). --- Nflag Note flag Lowercase letter that corresponds to a note flag from any of the files listed above. If this byte is blank, the note text is a continuation of the previous record. --- Ntext Note text --- C.-H. Joseph Lyu Hughes STX/NASA Gail L. Schneider SSDOO 1996Feb28 UNKNOWN UNKNOWN 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. VII_64.xml
