Constructor & Destructor Documentation

coordConv::Site::Site	(	double	meanLong,
		double	meanLat,
		double	elev
	)

Construct a new Site.

Initialize with no refraction correction and no polar wander.

Parameters

[in]	meanLong;	///< site longitude, ignoring pole wander (deg, positive eastward)
[in]	meanLat;	///< site latitude, ignoring pole wander (deg)
[in]	elev;	///< site elevation (meters above sea level)

Exceptions

std::range_error

if meanLat is not in range [-90, 90]
