Table Description:
This table is not available for ADQL queries and through the TAP endpoint.
Resource Description:
CALIFA has obtained spatially resolved spectroscopic information of a diameter selected sample of 600 galaxies in the Local Universe (0.005 < z < 0.03) using the PPAK integral field unit (IFU) on Calar Alto. This data release 2 provided access to the first 200 galaxies. It has been superseded by DR3, ivo://org.gavo.dc/califa/q3/s.
This RD is only provided for its datalink service, which in turn is referenced by the DR3 datalink service.
