S.F. Sanchez, L. Galbany, C.J.Walcher, R.Garcia-Benito, J.K., Barrera-Ballesteros

TL;DR
The CALIFA eDR provides a comprehensive, high-quality, and homogeneous dataset of 895 nearby galaxies with detailed spectral information, enabling extensive studies of galaxy properties across different types and masses.
Contribution
This work presents an extended, remastered data release of the CALIFA survey with improved data reduction and spatial resolution, covering a wide range of galaxy types and properties.
Findings
Homogeneous re-reduction of data with new cube-reconstruction algorithm
Extraction of stellar and gas properties using pyFIT3D
Sample is representative of the local galaxy population
Abstract
This paper describes the extended data release of the Calar Alto Legacy Integral Field Area (CALIFA) survey (eDR). It comprises science-grade quality data for 895 galaxies obtained with the PMAS/PPak instrument at the 3.5 m telescope at the Calar Alto Observatory along the last 12 years, using the V500 setup (3700-7500{\AA}, 6{\AA}/FWHM) and the CALIFA observing strategy. It includes galaxies of any morphological type, star-formation stage, a wide range of stellar masses (10 10 Msun ), at an average redshift of 0.015 (90\% within 0.005z0.05). Primarily selected based on the projected size and apparent magnitude, we demonstrate that it can be volume corrected resulting in a statistically limited but representative sample of the population of galaxies in the nearby Universe. All the data were homogeneous re-reduced, introducing a set of modifications to the…
