The PyCASSO database: Spatially resolved stellar population properties
  for CALIFA galaxies
  The Calar Alto Legacy Integral Field Area (CALIFA) survey, a pioneer in
integral field spectroscopy legacy projects, has fostered many studies
exploring the information encoded on the spatially resolved data on gaseous and
stellar features in the optical range of galaxies. We describe a value-added
catalogue of stellar population properties for CALIFA galaxies analysed with
the spectral synthesis code STARLIGHT and processed with the PyCASSO platform.
Our public data base (http://pycasso.ufsc.br/, mirror at
http://pycasso.iaa.es/) comprises 445 galaxies from the CALIFA Data Release 3
with COMBO data. The catalogue provides maps for the stellar mass surface
density, mean stellar ages and metallicities, stellar dust attenuation, star
formation rates, and kinematics. Example applications both for individual
galaxies and for statistical studies are presented to illustrate the power of
this data set. We revisit and update a few of our own results on mass density
radial profiles and on the local mass-metallicity relation. We also show how to
employ the catalogue for new investigations, and show a pseudo
Schmidt-Kennicutt relation entirely made with information extracted from the
stellar continuum. Combinations to other databases are also illustrated. Among
other results, we find a very good agreement between star formation rate
surface densities derived from the stellar continuum and the $\mathrm{H}\alpha$
emission. This public catalogue joins the scientific community's effort towards
transparency and reproducibility, and will be useful for researchers focusing
on (or complementing their studies with) stellar properties of CALIFA galaxies.
