TOPCAT provides some facilities for positional crossmatches
against tables which are exposed via Virtual Observatory web services
(Cone Search, Simple Image Access and Simple Spectral Access)
and general SQL-like matching (TAP).
These work rather differently from the other functions described
in this section, which operate on local tables, though conceptually
the result is similar.
See Section 6 for more details.
