Split spectra from the CALIFA DR3 cubes. This service serves one
spectrum each per pixel in each cube where there is at least one valid
spaxel. Where both V500 and COMB data is available, COMB spectra are
served. WARNING: The individual spectra are not independent. Also,
error estimates over wide spectral ranges based on the error estimates
served here are unreliable.
The Calar Alto Legacy Integral Field Area (CALIFA) survey provides
spatially resolved spectroscopic information for 667 galaxies, mainly
within the local universe (0.005 < z < 0.03).
CALIFA data was obtained using the PPAK integral field unit (IFU), with a
hexagonal field-of-view of 1.3 square arcmin, with a 100% covering factor
by adopting a three-pointing dithering scheme. has been taken in two
setups: V500 (6 Å bin size, 646 galaxies) and V1200 (2.3 Å bin size, 484
galaxies). A final product ("COMBO") combining both data sets, covering
3700-7500 Å at 6 Å bin size, is made availble for 484 galaxies.
CALIFA is a legacy survey, intended for the community. This is the (final)
Data Release 3. This is the VO/TAP publication with a simple web

Description:
There are many ways to access registry data. A fairly powerful one is
the Web Interface to the Relational Registry (WIRR for short) at
http://dc.g-vo.org/WIRR To actually speak to the VO services
discovered, clients speaking the service's protocols are still
required. In this tutorial, Topcat plays that role. Starting from a
simple use case, we work up to investigating the Tully-Fisher relation
in different bands using independently discovered resources.
