ADC_Keywords: Galaxy catalogs ; H I data
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.
