Abstract:
We present Rc-band surface photometry for 170 of the 203 galaxies in
GHASP, the Gassendi H-alpha survey of spirals, a sample of late-type
galaxies for which high-resolution Fabry-Perot Hα maps have
previously been obtained.
Description:
Our data set is constructed using new Rc-band observations taken at
the Observatoire de Haute-Provence, supplemented with Sloan Digital
Sky Survey archival data, obtained with the purpose of deriving
homogeneous photometric profiles and parameters. Our results include
Rc-band surface brightness profiles for 170 galaxies and ugriz
profiles for 108 of these objects. We catalogue several parameters
of general interest for further reference, such as total magnitude,
effective radius and isophotal parameters (magnitude, position angle,
ellipticity and inclination). We also perform a structural
decomposition of the surface brightness profiles using a
multi-component method to separate discs from bulges and bars, and to
observe the main scaling relations involving luminosities, sizes and
maximum velocities. We determine the Rc-band Tully-Fisher relation
using maximum velocities derived solely from Hα rotation curves
for a sample of 80 galaxies, resulting in a slope of -8.1±0.5,
zero-point of -3.0±1.0 and an estimated intrinsic scatter of
0.28±0.07. We note that, unlike the Tully-Fisher relation in the
near-infrared derived for the same sample, no change in the slope of
the relation is seen at the low-mass end (for galaxies with
Vmax<125km/s). We suggest that this different behaviour of the
Tully-Fisher relation (with the optical relation being described by a
single power law while the near-infrared has two), may be caused by
differences in the stellar mass-to-light ratio for galaxies with
Vmax<125km/s.
