The Calar Alto Legacy Integral Field Area (CALIFA) survey provides
spatially resolved spectroscopic information for 667 galaxies, mainly
within the local universe (0.005 &lt; z &lt; 0.03).

CALIFA data was obtained using the PPAK integral field unit (IFU), with a
hexagonal field-of-view of 1.3 square arcmin, with a 100% covering factor
by adopting a three-pointing dithering scheme.  has been taken in two
setups: V500 (6 Å bin size, 646 galaxies) and V1200 (2.3 Å bin size, 484
galaxies).  A final product ("COMBO") combining both data sets, covering
3700-7500 Å at 6 Å bin size, is made availble for 484 galaxies.

CALIFA is a legacy survey, intended for the community.  This is the (final)
Data Release 3.  This is the VO/TAP publication with a simple web
interface on top.  See http://califa.caha.es/ for the upstream
site.</description><table><name>califadr3.spectra</name><description> Metadata for individual spectra. Note that the spectra result from
