Description:
This tutorial is a comprehensive scientific usecase in which brown
dwarf candidates in 2MASS and SDSS are identyfied. The surveys are
queried using ADQL, and unncertainties in the data are solved with
TOPCAT and Aladin.

Description:
This tutorial was created for a physics teacher workshop (~ high
school level). It shows how to extract density fields and information
on dark matter halos from the CosmoSim database using SQL queries. It
is optimized for brevity.

Description:
This tutorial shows how to do first SQL-queries on cosmological
databases, including retrieving mass functions, extracting merger
trees or particles of a specific dark matter halo.
This is a view of the dust maps in the five orders, generated by
splitting the larger pixels from the higher orders into HEALPixes of
order 10. This means, in particular, that the spatial resolution for
all pixels with original_order!=10. Use this for convenient joins to
other tables.
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
