We present a catalogue of an HI-selected sample of 1129 low surface
brightness galaxies (LSBGs) searched from the alpha.40-SDSS DR7 survey. This
sample, consisting of various types of galaxies in terms of luminosity and
morphology, has extended the parameter space covered by the existing LSBG
samples. Based on a subsample of 173 LSBGs which are selected from our entire
LSBG sample to have the 2-horn shapes of the HI line profiles, minor-to-major
axial ratios (b/a) less than 0.6 and signal-to-noise ratio (S/N) of HI
detection greater than 6.5, we investigated the Tully-Fisher relation (TFr) of
LSBGs in the optical B, g and r bands and near-infrared J, H and K bands as
well. In optical bands, the LSBG subsample follows the fundamental TFr which
was previously defined for normal spiral galaxies. In NIR bands, the TFrs for
our LSBG subsample are slightly different from the TFrs for the normal bright
galaxies. This might be due to the internal extinction issue. Furthermore, the
mass-to-light ratio (M/L),disk scale length (h) and mass surface density
(sigma) for our LSBG subsample were deduced from the optical TFr results.
Compared with High Surface Brightness Galaxies(HSBGs), our LSBGs have higher
M/L, larger h and lower sigma than HSBGs.
