This paper describes the Second Public Data Release (DR2) of the Calar Alto Legacy Integral Field Area (CALIFA) survey. The data for 200 objects are made public, including the 100 galaxies of the First Public Data Release (DR1). Data were obtained with the integral-field spectrograph PMAS /PPak mounted on the 3.5 m telescope at the Calar Alto observatory. Two different spectral setups are available for each galaxy, (i) a low-resolution V500 setup covering the wavelength range 3745-7500 A with a spectral resolution of 6.0 A (FWHM); and (ii) a medium-resolution V1200 setup covering the wavelength range 3650-4840 A with a spectral resolution of 2.3 A (FWHM). The sample covers a redshift range between 0.005 and 0.03, with a wide range of properties in the color-magnitude diagram, stellar mass, ionization conditions, and morphological types. All the cubes in the data release were reduced with the latest pipeline, which includes improved spectrophotometric calibration, spatial registration, and spatial resolution. The spectrophotometric calibration is better than 6% and the median spatial resolution is 2´´ 4. In total, the second data release contains over 1.5 million spectra.

The SAMI Galaxy Survey: Instrument specification and target selection (2014, methodology): “Until recently, the largest IFU survey underway was the CALIFA survey (Sánchez et al. 2012; Walcher et al. 2014) using the Potsdam Multi-Aperture Spectrophotometer (PMAS; Roth et al. 2005) IFU on the 3.5m Calar Alto Telescope.”
OBSERVING STRATEGY FOR THE SDSS-IV/MaNGA IFU GALAXY SURVEY (2015, methodology): “This is highly undesirable from a science standpoint, and therefore typical fiber-bundle IFU surveys (e.g., Croom et al. 2012; Sánchez et al. 2012) dither their observations.”
New fully empirical calibrations of strong-line metallicity indicators in star forming galaxies (2016, background): “In this way our calibrations could be in principle applied to a great variety of cases, in particular to large IFU galaxy surveys that allow spatially resolved abundance studies (e.g CALIFA, Sánchez et al. 2012, MaNGA, Bundy et al. 2015 or SAMI, Croom et al. 2012).”
SDSS IV MaNGA – metallicity and nitrogen abundance gradients in local galaxies (2017, background): “Different calibrations, even when based on the same diagnostics ratios, can give results differing by up to 0.6 dex (Kewley & Ellison 2008; López-Sánchez et al. 2012; Peña-Guerrero et al. 2012).”
CALIFA : a diameter-selected sample for an integral field spectroscopy galaxy survey (2014, methodology): “…released data products from CALIFA are made available on the webpage http://www.caha.es/CALIFA In this paper we describe and discuss the target selection procedure for the Calar Alto Legacy Integral Field Area (CALIFA) survey (Sánchez et al. 2012a) and the resulting properties of the sample.”

SDSS-IV/MaNGA: SPECTROPHOTOMETRIC CALIBRATION TECHNIQUE (2015, background): “Of particular relevance in motivating our approach are the DiskMass, PINGS, CALIFA, and VENGA surveys, as all of these make use of fiber bundles with incomplete spatial coverage.”

Theoretical Challenges in Galaxy Formation (2016, background): “Recent integral field studies have significantly improved our understanding of the complex kinematics of galaxies (Bundy et al. 2015, Cappellari et al. 2011, de Zeeuw et al. 2002, Fogarty et al. 2014, Sánchez et al. 2012).”
THE DATA REDUCTION PIPELINE FOR THE SDSS-IV MaNGA IFU GALAXY SURVEY (2016, methodology): “Multiple methods exist for performing such image reconstruction (see §9.2); we choose to build our data cubes one image slice at a time using a flux-conserving variant of Shepard’s method similar to that used by the CALIFA pipeline (Sánchez et al. 2012).”
Mass-metallicity relation explored with CALIFA I. Is there a dependence on the star-formation rate?
