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:
These observations cover five star-forming regions in the Andromeda
galaxy (M31) with optical integral field spectroscopy. Each has a
field of view of roughly 1 kpc across, at 10pc physical resolution. In
addition to the calibrated data cubes, we provide flux maps of the Hβ,
[OIII]5007, Hα, [NII]6583, [SII]6716 and [SII]6730 line emission. Line
fluxes have not been corrected for dust extinction. All data products
have associated error maps.
