An H$\alpha$ kinematic survey of the $Herschel$ Reference Survey -- I.
  Fabry-Perot observations with the 1.93m telescope at OHP
  We present new 2D high resolution Fabry-Perot spectroscopic observations of
152 star-forming galaxies which are part of the $Herschel$ Reference Survey
(HRS), a complete $K$-band selected, volume-limited sample of nearby galaxies,
spanning a wide range in stellar mass and morphological type. Using improved
data reduction techniques that provide adaptive binning based on Voronoi
tessellation, using large field-of-view observations, we derive high spectral
resolution (R$>$10,000) H$\alpha$ datacubes from which we compute H$\alpha$
maps and radial 2D velocity fields that are based on several thousand
independent measurements. A robust method based on such fields allows us to
accurately compute rotation curves and kinematical parameters, for which
uncertainties are calculated using a method based on the power spectrum of the
residual velocity fields. We check the consistency of the rotation curves by
comparing our maximum rotational velocities to those derived from HI data, and
computing the $i$-band, NIR, stellar and baryonic Tully-Fisher relations. We
use this set of kinematical data combined to those available at other
frequencies to study for the first time the relation between the dynamical and
the total baryonic mass (stars, atomic and molecular gas, metals and dust), and
derive the baryonic and dynamical main sequence on a representative sample of
the local universe.
