APFS TGAS Simple Query

This service computes apparent and/or intermediate places of the stars in the TGAS (2016).

The positions can be given either in the CIO system (default) or the old equinox system.

If you give a position or an object resolvable by Simbad, the service will choose the nearest TGAS star for the ephemeris.

Enter a TGAS source identifier, or a (decimal, comma-separated) position or simbad identifier to use the closest TGAS star.
