Function Documentation

double lupnt::CoordinateScaleFactor(CoordinateScale scale)

Look up the IAU defining scale factor (1 - L_x) for a CoordinateScale.

TCB/TCG/TCL (proper “coordinate time” scales) map to 1.0, while TDB/TT/TL map to 1 - L_B/1 - L_G/1 - L_L respectively. Used by CoordinateScaleRatio/CheckedCoordinateScaleRatio to form the ratio between two scales.

Parameters:

scale – Coordinate scale

Returns:

IAU defining scale factor for scale
