Member Function Documentation

void tcc::Weath::computeRefCo	(	double &	refCoA,
		double &	refCoB,
		double	wavelen,
		double	elev,
		double	lat
	)		const

Compute refraction coefficients A and B

unrefractedZD = refractedZD + deltaZD, where: deltaZD = A tan(refractedZD) + B tan(refractedZD)^3 refractedZD is the observed zenith distance on earth (rad) unrefractedZD is the zenith distance in vacuum (rad) (The equation is backwards from what we need to compute refracted zenith distance.)

Parameters

[out]	refCoA	refraction coefficient A (deg)
[out]	refCoB	refraction coefficient B (deg)
[in]	wavelen	wavelength (Angstroms)
[in]	elev	height of the observer above sea level (m)
[in]	lat	latitude of the observer (deg)
