Abstract:
Using both the Arecibo 305m and the Nancay decimetric 100-m class
radio telescopes, we have observed the H I line of 116 Low Surface
Brightness (LSB) galaxies from the Bothun et al. (1985AJ.....90.2487B 1985AJ.....90.2487B)
subset of LSB galaxies in the Uppsala General Catalog. Combining our
results with previous studies done on the Bothun et al.
(1985AJ.....90.2487B 1985AJ.....90.2487B) catalog results in a well-defined catalog of H I
properties of 526 LSB galaxies ranging in redshift space from
0≤z≤0.1. With this catalog in hand, we have been able to explore the
parameter space occupied by LSB galaxies more completely than has been
previously possible.
Description:
Previously published values for the galaxies observed.
Table 1 lists the magnitude, mean central surface brightness, diameter
at a surface brightness of 25mag/arcsec^2, morphological type, and
optical inclination.
Table2 lists the region of velocity space searched for the survey as
well as any radio frequency interference encountered.
Table 3 lists the HI properties observed and inferred from Arecibo and
Nancay observations. These include the heliocentric velocity, velocity
widths at 20% and 50% of the peak values, the measured HI flux, and
any values found in the literature.
