G_POSANG

#define G_POSANG   "GSkyDir::posang(GSkyDir&, std::string&)"

Definition at line 41 of file GSkyDir.cpp.

G_SET

#define G_SET   "GSkyDir::set(std::string&)"

Set sky direction from coordinate string.

Parameters

[in]

coord

Coordinate string.

Sets sky direction from coordinate string.

In addition, names of a few emblematic sources are translated into a sky direction using CDS coordinates. The following names are implement (case insensitive):

• "Crab" (l=184.5574843227357, b=-5.7843392171240)
• "Vela" (l=263.55197071, b=-2.78725587)
• "CygX-1" (l=71.3349982655144, b=3.0668346317201)

Function Documentation

operator!=()

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 1644 of file GSkyDir.cpp.

operator==()

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.
