    JMA acknowledges support from the European Research Council Starting Grant (SEDmorph; P.I. V. Wild).We describe and discuss the selection procedure and statistical properties of the galaxy sample used by the Calar Alto Legacy Integral Field Area (CALIFA) survey, a public legacy survey of 600 galaxies using integral field spectroscopy. The CALIFA "mother sample" was selected from the Sloan Digital Sky Survey (SDSS) DR7 photometric catalogue to include all galaxies with an r-band isophotal major axis between 45 '' and 79 : 2 '' and with a redshift 0 : 005 M-r > -23 : 1 and over a stellar mass range between 10(9.7) and 10(11.4) M-circle dot. In particular, within these ranges, the diameter selection does not lead to any significant bias against - or in favour of - intrinsically large or small galaxies. Only below luminosities of M-r = -19 (or stellar masses <10(9.7) M-circle dot) is there a prevalence of galaxies with larger isophotal sizes, especially of nearly edge-on late-type galaxies, but such galaxies form <10% of the full sample. We estimate volume-corrected distribution functions in luminosities and sizes and show that these are statistically fully compatible with estimates from the full SDSS when accounting for large-scale structure. For full characterization of the sample, we also present a number of value-added quantities determined for the galaxies in the CALIFA sample. These include consistent multi-band photometry based on growth curve analyses; stellar masses; distances and quantities derived from these; morphological classifications; and an overview of available multi-wavelength photometric measurements. We also explore different ways of characterizing the environments of CALIFA galaxies, finding that the sample covers environmental conditions from the field to genuine clusters. We finally consider the expected incidence of active galactic nuclei among CALIFA galaxies given the existing pre-CALIFA data, finding that the final observed CALIFA sample will contain approximately 30 Sey2 galaxies.Peer reviewe

    The observations were carried out with the Potsdam Multi-Aperture Spectrometer 112, PMAS in the PPaK mode 137 at the 3.5m telescope of Calar Alto observatory. PPaK contains 382 fibers of 2.7" diameter each, and a 74"x64" FoV 73. Each galaxy is observed with two spectral settings, V500 and V1200, with spectral resolutions ~6Å (FWHM) and 2.3Å, respectively. The V500 grating covers from 3745 to 7300Å, while the V1200 covers 3650-4840Å. (2 data files)

    There are two fundamentally different samples of galaxies in the CALIFA DR3: (1) Galaxies that were targeted because they were part of the CALIFA mother sample that is fully described and characterized in Walcher et al. (2014A&A...569A...1W). This sample is called the CALIFA Main Sample. (2) The CALIFA Extension Sample, which is a heterogeneous set of galaxies observed for various reasons as part of different ancillary science projects within the CALIFA collaboration. The DR3 release is the combination of the Main Sample and the Extension Sample. (1 data file)
