In helixcn/skycalc: Computational Astronomy in R based on PJ Naughter's AA+ library

Description

CAACoordinateTransformation_Equatorial2Horizontal

Usage

CAACoordinateTransformation_Equatorial2Horizontal(LocalHourAngle, Delta, Latitude)

Arguments

LocalHourAngle	LocalHourAngle The local hour angle, measured westwards from the South.
Delta	Delta The declination in degrees.
Latitude	Latitude The standard latitude of the position in degrees.

Value

Returns the converted horizontal coordinates in a CAA2DCoordinate class. The x value in the class corresponds to the azimuth in degrees and the y value corresponds to the altitude in degrees.
