Tables available are the following:
All 10,000+ VizieR tables with position. For each VizieR table, we have kept the default VizieR columns plus positional errors, photometry columns and associated errors if they were not already included.
SIMBAD. A view of the SIMBAD bibliographical database with the following fields: main object name, position, errors on position, BVRJHK magnitudes, object type, proper motion, spectral type, and number of bibliographical references. This view is updated each day, so that it reflects the latest updates in the database.
user-uploaded tables. You can upload your own table in one of the following formats : VOTable, FITS table or CSV (Comma separated values) table (see section 4.2 for more details).
Large tables (larger than 10 million rows) have been modified with respect to original VizieR tables. Positional errors have been reformatted to be expressed as an ellipse with 3 parameters: major axis, minor axis and position angle.

Consult the VizieR service for a detailed description of each field above.
WARNING: some data have been modified from the original catalogues:
Positions are given in FK5 J2000 (at epoch 2000 if proper motion available)
Positional errors have been standardized: they are all given in arcseconds in the form of a circle or an ellipse with semi-minor, semi-major axis and position angle
For catalogues containing proper motions such as the USNO-B1.0, although positions are given at epoch 2000, positional errors do not take into account proper motion uncertainties (will be done in a future release)
For all catalogues, and especially the USNO-B1.0, a threshold of 40 has been put on magnitudes: higher values are set to 40. (If it is annoying for you, contact us, it can easily be changed).
If those limitations are a problem for you, contact us.
SDSS DR7 : Only primary source (mode=1) and object of type GALAXY or STAR (cl = 3 or 6) are available.
SDSS DR8 : Only primary source (mode=1) are available.
Versions of Galex AIS and MIS are the catalogues available here: http://dolomiti.pha.jhu.edu/uvsky/.
