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 service exposes about 0.5 million light curves of stars
classified as variable by the Gaia analysis system through the VO SSAP
protocol. The lightcurves are published per-band and are also
available through obscore.
This services provides 1D spectra from DR5 of LAMOST (Large Sky Area
Multi-Object Fiber Spectroscopic Telescope) through SSAP;
data is served both in VO-standard SDM and, via datalink, the original
SDSS-inspired FITS described in
http://dr5.lamost.org/doc/data-production-description .
The LOFAR Two Meter Sky Survey LoTSS DR2
(:bibcode:`2022A&A...659A...1S`) obtained radio data from 27% of the
northern sky between 120 and 168 MHz in the year 2014 through 2020. This
service publishes polarization spectra of extragalactic radio sources
(radio galaxies and blazars) and the rotation measures derived from them.
We also give redshifts for all sources. The data has a spatial resolution
of 20 arcsec.
