Information on Service 'GAVO CALIFA DR2 Cubes'

[Use this service from your browser]

Further access options are discussed below

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 It has been superseded by DR3, ivo://org.gavo.dc/califa/q3/s.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.

For a list of all services and tables belonging to this service's resource, see Information on resource 'CALIFA (Calar Alto Legacy Integral Field spectroscopy Area) survey DR2'

Overview

You can access this service using:

This service is not published. This can mean that it was deemed too unimportant, for internal use only, or is just a helper for a published service. Equally likely, however, it is under development, abandoned in development or otherwise unfinished. Exercise caution.

Other services provided on the underlying data include:

Input Fields

The following fields are available to provide input to the service (with some renderers, some of these fields may be unavailable):

VOTable Output Fields

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.
