inlinevirtual |
This method is heavily used and therefore needs to be very fast. The returned SphericalCap doesn't have to be the smallest one, but smaller is better.
Reimplemented from SphericalRegion.
|
virtual |
It can be used for safe computation of intersection/union in the general case.
Implements SphericalRegion.
|
virtual |
The format is ["POINT", [ra, dec]], with ra dec in degree in ICRS frame.
Implements SphericalRegion.
