NED Abstract

Copyright by Royal Astronomical Society. 2005MNRAS.360.1201H BH{alpha}BAR: big H{alpha} kinematicala sample of barred spiral galaxies - I. Fabry-Perot observations of 21 galaxies Hernandez, O.; Carignan, C.; Amram, P.; Chemin, L.; Daigle, O. Abstract. We present the H{alpha} gas kinematics of 21 representative barred spiral galaxies belonging to the BH{alpha}BAR sample. The galaxies were observed with FaNTOmM, a Fabry-Perot integral-field spectrometer, on three different telescopes. The three-dimensional data cubes were processed through a robust pipeline with the aim of providing the most homogeneous and accurate data set possible useful for further analysis. The data cubes were spatially binned to a constant signal-to-noise ratio, typically around 7. Maps of the monochromatic H{alpha} emission line and of the velocity field were generated and the kinematical parameters were derived for the whole sample using tilted-ring models. The photometrical and kinematical parameters (position angle of the major axis, inclination, systemic velocity and kinematical centre) are in relative good agreement, except perhaps for the later-type spirals.
