The SkyFrame constructor function is particularly simple and a
SkyFrame with default attributes is created as follows:
#include "ast.h"
AstSkyFrame *skyframe;
...
skyframe = astSkyFrame( "" );
Such a SkyFrame would represent the default celestial coordinate
system which, at present, is the FK5 (J2000.0) equatorial system.
