### 5.6 Matching against a Remote Table

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). This works rather differently from the other functions described in this section, which operate on local tables, though conceptually the result is similar. See Appendix A.9.1.3 for more details.
