Data Fields
double	height
	[m] altitude above sea level
double	humidity
	[%] Relative humidity.
double	latitude
	[deg] geodetic (ITRS) latitude; north positive
double	longitude
	[deg] geodetic (ITRS) longitude; east positive
double	pressure
	[mbar] atmospheric pressure for optical refraction
double	temperature
	[C] temperature (degrees Celsius); for optical refraction

Detailed Description

data for an observer's location on the surface of the Earth. The atmospheric parameters are used only by the refraction function called from function 'equ2hor'. Additional parameters can be added to this structure if a more sophisticated refraction model is employed.
