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 It has been superseded by DR3, ivo://org.gavo.dc/califa/q3/s.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

Overview

You can access this service using:

This resource is not (directly) 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 some 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.
