The following is the "ReadMe" document that describes this ADC catalog. You can 
access the files described here from the anonymous FTP directory 
ftp://adc.gsfc.nasa.gov/pub/adc/archives/catalogs/7/7136/. Or you can preview 
the data files. (Please note that the ADC data viewer does not currently work 
with FITS files or datasets that don't have standard documents. The viewer has 
not been tested against all possible data files. It may not work for some or all 
files for this catalog. See the ADC Archive Data Viewer Interface page for the

Description:
   This catalog is a compilation of weighted mean H I parameters for 6439
   galaxies. Raw 21-cm line widths have been reduced to a common system of
   widths at 20 and 50 percent of the peak intensity. They have been
   corrected for velocity resolution effects and tested for homogeneity.
   The H I fluxes, converted to uniform units, have been corrected for
   beam-filling effects. The catalog includes identification and alternate
   names, B1950 positions, line widths, H I flux, and heliocentric radial
   velocity. Details, including references to the original data, can be
   found in the published version.

Note on ID:
   PGC Number according to the Catalogue of Principal Galaxies
   (Paturel et al., 1989 and 1989a)
Note on name:
   priority: NGC, IC, UGC, ESO, MCG, UGCA, Mk, DDO, CGCG, Fairall, Arakelian, 
        U.Michigan, Zwicky-compacts, VV, Arp, VCC, Weinberger, IRAS, KUG
   (see Paturel et al., 1989)
Note on W20:
   Weighted mean of 21cm line width at the level 20% of the peak.
   This width is corrected for velocity resolution.
Note on W50:
   Weighted mean of 21cm line width at the level 50% of the peak.
   This width is corrected for velocity resolution.
Note on logS:
   Log of the weighted mean HI-flux corrected for beam-filling effect.
   This flux and the associated error are both expressed in:
        log(10^-24 W*m^-2).
Note on RV:
   Weighted mean of the heliocentric radial velocity expressed in
        c*delta lambda/lambda.
