SIMBAD: Query by identifiers
Gaia DR2: For now, Gaia DR2 data are not in SIMBAD, it is available in Vizier. The CDS will perform a cross-identification of Gaia DR2 with the astronomical objects in the SIMBAD bibliographic database. This will be done with very strict criteria in order to avoid erroneous cross-identifications. Especially, only the 6.5 milllions objects with subarseconds coordinates will be searched in Gaia DR2. Expected to be ready on June 30, 2018.
Query by identifiers can be done by
- full identifiers
- partial identifiers using wildcards ('?' = one char, '*' = any string, including
an empty one (no char), '[xyz]' = one char among the list.
If an identifier contains a wildcard character (i.e. '**'), these characters must be
escaped by a backslash (\) to avoid them to be interpreted as a wildcard.
|HD *0000 ||returns all HD objects having the HD identifier ending with 4 zeros|
|HD 10? ||returns HD 100, 101, ..., 109.|
Example: \*\* *AB
- query around an object, with a radius definition
- a whole catalogue.
- Query by lists of objects
