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
interface on top. See http://califa.caha.es/ for the upstream
site.
This tutorial uses SPLAT-VO to search the VO registry for spectra of
galaxies and quasars. From the obtained spectra, the Hydrogen Lyman
Alpha line will be used to compute redshift and velocity

Description:
The First Byurakan Survey (FBS) is the largest and the first systematic
objective prism survey of the extragalactic sky. It covers 17,000 sq.deg.
in the Northern sky together with a high galactic latitudes region in the
Southern sky. The FBS has been carried out by B.E. Markarian, V.A.
Lipovetski and J.A. Stepanian in 1965-1980 with the Byurakan Observatory
102/132/213 cm (40"/52"/84") Schmidt telescope using 1.5 deg. prism. Each
FBS plate contains low-dispersion spectra of some 15,000-20,000 objects;
the whole survey consists of about 20,000,000 objects.
Spectra from the Flash and Heros Echelle spectrographs developed at
Landessternwarte Heidelberg and mounted at La Silla and various other
observatories. The data mostly contains spectra of OB stars. Heros was
the name of the instrument after Flash got a second channel in 1995.

This is a re-publication the Gaia DR3 RP/BP spectra in the IVOA Spectral
Data Model. It presents the continous spectra in sampled form, using a
Monte Carlo scheme to decorrelate errors, elaborated in this resource's
reference URL. The underlying tables are also available for querying
through TAP, which opens some powerful methods for mass-analysing the data.
