The CeSAM Virtual Observatory Server's TAP end point. The Table Access
Protocol (TAP) lets you execute queries against our database tables,
inspect various metadata, and upload your own data. It is thus the
VO's premier way to access public data holdings.
Tables exposed through this endpoint include: main from the aspic_6df schema, g02, g09g12g15 from the aspic_gama schema, main from the aspic_muse_wide schema, w1, w1_video, w4 from the aspic_vipers schema, cosmos, ecdfs from the aspic_vuds schema, catalogue, spectra from the el_cosmos_dr1 schema, spectra from the gama_dr3 schema, obscore from the ivoa schema, spectra from the muse_wide_dr1 schema, bolshoi2022, uchuu2022 from the sides schema, columns, groups, key_columns, keys, schemas, tables from the tap_schema schema, spectra from the vipers_dr2 schema, spectra from the vuds_dr1 schema, spectra from the zcosmos_20k schema.
The overall goal of this tutorial is to become familiar with VOSpec.
For that, we are going to build the Spectral Energy Distribution (SED)
of two Herbig Ae/Be stars, compare them and categorise them as group 1
or group 2 Herbig Ae/Be stars.
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
Within this intermediate use case you learn about supernovae (see
also the tutorial “Distance to the Crab Nebula“,
ivo://edu.euro-vo.org/tutorials/08_m1_distance) and determine the
celestial coordinates of a just discovered candidate supernova on an
provided image without astrometric calibration. This use case provides
a glimpse of an activity that is representative of the practical tasks
that astronomers have to perform when they analyze data.
The publication software DaCHS comes with a preconfigured authority
x-unregistred. Before version 2.3, it would let records with this null
authority into the VO. This authority's exclusive purpose is to let us
delete any such records.
The DaCHS Server for LMD's TAP end point. The Table Access
Protocol (TAP) lets you execute queries against our database tables,

VO's premier way to access public data holdings.
Tables exposed through this endpoint include: epn_core from the mars_dust schema, epn_core from the mcd schema, columns, groups, key_columns, keys, schemas, tables from the tap_schema schema, epn_core from the vcd schema.
Data Discovery Using the Virtual Observatory Registry

Description:
There are many ways to access registry data. A fairly powerful one is
the Web Interface to the Relational Registry (WIRR for short) at
http://dc.g-vo.org/WIRR To actually speak to the VO services
discovered, clients speaking the service's protocols are still
required. In this tutorial, Topcat plays that role. Starting from a
simple use case, we work up to investigating the Tully-Fisher relation
in different bands using independently discovered resources.
