angle_diff

lsst.ts.utils.angle_diff(angle1: Union[astropy.coordinates.Angle, float], angle2: Union[astropy.coordinates.Angle, float]) → astropy.coordinates.Angle

Return angle1 - angle2 wrapped into the range [-180, 180) deg.

Parameters

angle1astropy.coordinates.Angle or float

Angle 1; if a float then in degrees

angle2astropy.coordinates.Angle or float

Angle 2; if a float then in degrees

Returns

diffastropy.coordinates.Angle

angle1 - angle2 wrapped into the range -180 <= diff < 180 deg.
