getRADecForSource

Return to directory of Todd's CASA extensions

Calls msmd.sourcedirs and extracts the RA/Dec for the specified source ID, in sexagesimal format. It chooses the first row where the SOURCE_ID column matches the requested source. It does not currently (CASA 4.4) support ephemeris objects. See also getRADecForField which uses ms.getfielddirmeas, which does support ephemeris objects.

Usage:

au.getRADecForSource(vis, source)

Inputs:

• vis: measurement set
• source: source ID (integer or string integer) or source name

Example:

CASA <6>: au.getRADecForSource('uid___A002_Xa56b1d_X174.ms',0)
  Out[6]: '02:38:38.93011, +016:36:59.274620'
