Function Documentation

bool operator!=	(	const GSkyDir &	a,
		const GSkyDir &	b
	)

Non equality operator.

Parameters

[in]	a	First sky direction.
[in]	b	Second sky direction.

Definition at line 1495 of file GSkyDir.cpp.

bool operator==	(	const GSkyDir &	a,
		const GSkyDir &	b
	)

Equality operator.

Parameters

[in]	a	First sky direction.
[in]	b	Second sky direction.

Compare two sky directions. If the coordinate is at the pole, the Right Ascension or Longitude value is irrelevant.

Comparisons are done dependent on the available coordinate system. This speeds up things and avoids unnecessary coordinate transformations.
