altaz_to_righthanded_cartesian#
- ctapipe.coordinates.altaz_to_righthanded_cartesian(alt, az, distance=1.0)[source]#
Turns an alt/az coordinate into a 3d direction in a right-handed coordinate system. This is because azimuths are in a left-handed system.
See e.g: astropy/astropy#5300
- Parameters:
- alt: u.Quantity
altitude
- az: u.Quantity
