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.
The LIFE Target Star Database contains information useful
for the planned `LIFE mission`_ (mid-ir, nulling
interferometer in space). It characterizes possible
target systems including information about stellar,
planetary and disk properties. The data itself is mainly
a collection from different other catalogs.
Note that LIFE's target database is living
data. The content – and to some extent even structure – of these
tables may change at any time without prior warning.

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.

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.

Description:
This tutorial demonstrates how to use several standard tools of the
Virtual Observatory (VO) for data mining and multiple waveband data
analysis. The step-by-step application below focuses on towards
applications in the gamma-ray and high energy domain, but also
involves observational data from other wavebands.

Description:
NMDB serves the data of roughly 50 stations across the globe
measuring ground-based cosmic ray intensities at minute cadence.
Cosmic rays are detected for primary particles of energies up to 15
GeV depending on station magnetic latitude.
