The Stc class is an implementation of the IVOA STC class which forms part of the IVOA Space-Time Coordinate Metadata system. See:

http://hea-www.harvard.edu/$\sim$arots/nvometa/STC.html

The Stc class does not have a constructor function of its own, as it is simply a container class for a family of specialised sub-classes including StcCatalogEntryLocation, StcResourceProfile, StcSearchLocation and StcObsDataLocation.

astStc

The Stc class inherits from the Region class.

In addition to those attributes common to all Regions, every Stc also has the following attributes:

• RegionClass: The class name of the encapsulated Region.

In addition to those functions applicable to all Regions, the following functions may also be applied to all Stc’ s:

• astGetStcRegion: Get a pointer to the encapsulated Region

• astGetStcCoord: Get information about an AstroCoords element

• astGetStcNCoord: Returns the number of AstroCoords elements in an Stc
