User manual

The general form (“All VizieR”) lets you give either the name or the number of the
catalogue directly (CDS/ADC nomenclature) in the specific field, or to obtain a list of
catalogues that fulfil some criteria (free text, authors, … wavelengths, mission names or
astronomical keywords). This query can be restrained by a cone search specified by the
“Target/Radius” fields. This functionality is extremely useful to determine all the
catalogues that have at least one observation in this field. You can then check in the list,
the catalogue(s) for which you would like to get the sources and then click on the
“SUBMIT” button.
Tip: A click gives a catalogue plane. It can be useful to spread your results in different
planes in order to manipulate them more easily afterwards.
“Surveys “and “Missions”
Both other forms dedicated to VizieR gather, for the sake of convenience, all the large
surveys on one side, and on the observations lists on the other side, that are available in
VizieR. These distinctive catalogues are presented as a clickable list.
