The Calar Alto Legacy Integral Field Area survey is one of the largest IFS surveys performed to date. At its completion it will comprise 600 galaxies, observed with the PMAS spectrograph in the PPAK mode, covering the full spatial extent of these galaxies up to two effective radii. The wavelength range between 3700 and 7500 Å is sampled with two spectroscopic configurations, a high resolution mode (V1200, R~1700, 3700-4200 Å), and a low resolution mode (V500, R~850, 3750-7500 Å). A detailed explanation of the survey is given in the CALIFA Presentation Article (Sánchez et al. 2012).
The first CALIFA Data Release (DR1) provides to the public the fully reduced and quality control tested datacubes of 100 objects in both setups (V500 and V1200). Each datacube contains ~2000 individual spectra, thus in total this DR comprises ~400,000 individual spectra. The details of the data included in this DR are described in the CALIFA DR1 Article (Husemann et al. 2012). The complete list of the DR1 objects for which we deliver data can be found in the following webpage.
The main characteristics of the galaxies included in the full CALIFA mother sample, a subset of which are delivered in this DR, will be given in the CALIFA sample characterization article (Walcher et al. in prep.). This article will provide detailed information of the photometric, morphological and environmental properties of the galaxies, and a description of the statistical properties of the full sample.
