Haα kinematics of the SINGS nearby galaxies survey - I

This is the first part of an Hα kinematics follow-up survey of the Spitzer Infrared Nearby Galaxies Survey (SINGS) sample. The data for 28 galaxies are presented. The observations were done on three different telescopes with Fabry-Perot of New Technology for the Observatoire du mont Megantic (FaNTOmM), an integral field photon-counting spectrometer, installed in the respective focal reducer of each telescope. The data reduction was done through a newly built pipeline with the aim of producing the most homogenous data set possible. Adaptive spatial binning was applied to the data cubes in order to get a constant signal-to-noise ratio across the field of view. Radial velocity and monochromatic maps were generated using a new algorithm, and the kinematical parameters were derived using tilted-ring models. © 2006 RAS.
