Class VO

Description:
Virtual Observatory-specific functions. Some of these are for rather technical purposes.

The UCD parsing functions are based on Grégory Mantelet's library Ucidy corresponding to UCD1+ 1.4, and the VOUnit parsing functions are based on Norman Gray's library Unity corresponding to VOUnits 1.0.

TFCat refers to the Time-Frequency Radio Catalogues format, TFCat 1.0.
