Abstract:
We present a homogeneous compilation of HI spectral parameters
extracted from global 21cm line spectra for some 9000 galaxies in the
local universe (heliocentric velocity -200<V☉<28,000km/s)
obtained with a variety of large single-dish radio telescopes but
reanalyzed using a single set of parameter extraction algorithms.
Corrections to the observed HI line flux for source extent and
pointing offsets and to the HI line widths for instrumental broadening
and smoothing are applied according to model estimates to produce a
homogenous catalog of derived properties with quantitative error
estimates. Where the redshift is available from optical studies, we
also provide flux measurements for an additional 156 galaxies
classified as marginal HI detections and rms noise limits for 494
galaxies classified as nondetections.
Description:
In addition to the HI spectra already contained in the digital
archive, new HI line observations were conducted with the Arecibo 305m
telescope and its Gregorian optics system between 2001 September and
November.

Note (1): The morphological type code following the RC3 (Cat. VII/155) system.
Classification comes either from the UGC (Cat. VII/26) or ESO
(Cat. VII/34) catalogs or from our own visual examination of the
POSS-I prints.
Note (2): Algorithm uncorrected velocity width.
Note (3): Taken to be the sum in quadrature of the measurement error and the
estimated error in broadening corrections.
Note (4): Smoothing code, defined as follows:
H = single Hanning only;
B = Hanning plus three-channel boxcar.
Note (5): Width quality code, defined as follows:
G = good;
F = fair;
S = single peak;
P = poor quality for TF applications;
C = confused;
A = shows absorption.
