The CALIFA Survey (Calar Alto Legacy Integral Field Area Survey) is an astronomical project to map 600 galaxies with integral field spectroscopy (IFS), to allow detailed studies of these objects.
The data are taken at the Calar Alto Observatory in Spain.
The CALIFA project addresses a number of open questions in galaxy evolution, among them: CALIFA data are made public through regular releases (DR).
DR1, containing 200 data cubes of 100 galaxies, was released 1 November 2012.
[1] DR2, containing 400 data cubes of 200 galaxies, was released on 1 October 2014.
