VII/136 Extragalactic Data Base II. The H I Data (Bottinelli+ 1990) ============================================================================ An Extragalactic Data Base II. The H I Data Bottinelli, L. Gouguenheim L., Fouque P., and Paturel G. =1990A&AS...82..391B ============================================================================ 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.

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. ----------------------------------------------------------------------------- References: Paturel G., Fouque P., Bottinelli L., Gouguenheim L., 1989, Astron.
