DegreeToRightAscension()

template<typename T >

void EGXPhys::DegreeToRightAscension	(	const T	decimalDegree,
		T &	hour,
		T &	minute,
		T &	second
	)

Converts an angle in (decimal) degree to hours minutes seconds (HMS). \({HH}^{h}{MM}^{m}{SS.SS}^{s}\) format.

\[hour=trun(\frac{\alpha_{deg}}{15})\]

\[minute=trun(60 * |\frac{\alpha_{deg}}{15} - hour|)\]

\[second=60 * ((60 * |\frac{\alpha_{deg}}{15} - hour|)-minute)\]

.

Parameters

decimalDegree	\(\alpha_{deg}\ (deg)\) is the angle in (decimal) degrees.
hour	\(RA_h\ (hour)\) is the angle in hours.
minute	\(RA_m\ (min)\) is the angle in minutes in whole numbers. Note that this is 1/60 of an hour. It is not equal to arcminutes.
second	\(RA_s\ (sec)\) is the angle in seconds. Note that this is 1/60 of a minute, not arcminute. It is not equal to arcseconds.
