Method Details

getEquinox(self)

source code

returns a datetime.datetime instance for the frame's equinox.

It will return None if no equinox is given, and it may raise an STCValueError if an invalid equinox string has been set.

asTriple(self)

source code

returns a triple defining the space frame for spherc's purposes.

This is for the computation of coordinate transforms. Since we only do coordinate transforms for spherical coordinate systems, this will, for now, raise STCValueErrors if everything but 2 or 3D SPHERICAL flavours. The other cases need more thought anyway.
