Function Details

parses a SIAPv2 geometry spec to a pgsphere object.

Parse errors raise validation errors for fieldName.

tries to infer RA and DEC from posStr.

In contrast to base.parseCooPair, we are quite strict here and just try to cope with some bad clients that leave out the comma.

returns an SQL fragment for a SIAP query for bboxes.

The SQL is returned as a WHERE-fragment in a string. The parameters are added in the sqlPars dictionary.

parameters is a dictionary that maps the SIAP keywords to the values in the query. Parameters not defined by SIAP are ignored.
