10.6.21 VO

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.

ucdStatus( ucd )
Returns a token string giving the category of UCD compliance. UCD1+, UCD1 and SIAv1 ("VOX:")-style UCDs are recognised.

Possible return values are currently:

In the case of non-compliant values, more information can be found using the ucdMessage function.

ucdMessage( ucd )
Returns a human-readable message associated with the parsing of a UCD. This is expected to be empty for a fully compliant UCD, and may contain error messages or advice otherwise.

vounitStatus( unit )
Returns a token string giving the category of VOUnits compliance.

Possible return values are currently:

In the case of non-compliant values, more information can be found using the vounitMessage function.

vounitMessage( unit )
Returns a human-readable message associated with the parsing of a unit string. This is expected to be empty for a string fully compliant with VOUnits, and may contain error messages or additional information otherwise.
