Abstract:
We present the Fabry-Perot observations obtained for a new set of
108 galaxies in the frame of the Gassendi Hα survey of SPirals
(GHASP). The GHASP survey consists of 3D Hα data cubes for 203
spiral and irregular galaxies, covering a large range in morphological
types and absolute magnitudes, for kinematics analysis. The new set of
data presented here completes the survey. The GHASP sample is by now
the largest sample of Fabry-Perot data ever published. The analysis of
the whole GHASP sample will be done in forthcoming papers. Using
adaptive binning techniques based on Voronoi tessellations, we have
derived Hα data cubes from which are computed Hα maps,
radial velocity fields as well as residual velocity fields,
position-velocity diagrams, rotation curves and the kinematical
parameters for almost all galaxies.
Description:
The GHASP survey was originally selected to be a subsample
complementing the radio survey Westerbork survey of HI in SPirals
galaxies (WHISP) providing HI distribution and velocity maps for
about 400 galaxies (http://www.astro.rug.nl/whisp). The first set of
GHASP galaxies was selected from the first WHISP website list but some
of them have never been observed by WHISP.
