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 .
Since 1973, the 18-cm lines of the OH radical have been
systematically observed in a number of comets with the Nançay radio
telescope. This allowed an evaluation of the cometary water production
rates and their evolution with time, as well as a study of several
physical processes: the excitation mechanisms of the OH radio lines,
the expansion of the cometary atmospheres, their anisotropy in
relation with non-gravitational forces, the Zeeman effect in relation
with the cometary magnetic field. The Nançay observations of 53
cometary apparitions between 1982 and 2009 are now organized in this
database.
Convolution of normalized synthetic stellar spectra.
Up to 3 successive convolutions are allowed on a adjustable portion of a synthetic spectrum, in order to mimic an observable.
These convolutions acount for macroturbulence velocity, rotational velocity and instrumental profile.
Finally, the output can be Doppler-shifted in order to take into account a stellar radial velocity.
The stellar spectra service is a compilation of several libraries
distributed by large observatories, which are intended to calibrate
telescopic observations. It currently provides access to two libraries
of reference stars distributed by ESO (composite spectra:

and NASA IRTF (observations from SpeX:

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 Visual and Infrared Mapping Spectrometer (VIMS) instrument
onboard the Cassini spacecraft observed the system of Saturn,
acquiring spectral cubes in the range 0.4-5.2 microns. This service
focuses on Saturn satellites, and provides access to calibrated and
ancillary data, computed as described here:
https://vims.univ-nantes.fr/info/isis-calibration. It also provides
direct links to a larger web site with previews.
