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.
The MAGIC project observes the VHE sky (GeV~TeV) through Cherenkov
radiation events. The project is operating since 2004 and with the
support from the Spain-VO team they provide data access through a
VO-SSAP and web services. This service re-publishes the data with
homogeneized in flux units (given here in 'erg/(s.cm2)'). Photon
energy values in are transfomred to frequencies.
