The rotation type specifies the meaning of the rotation angle.
Only Object and Horizon are typically used for science (or None if your instrument does not have a rotator).
Object rotation is the only choice that makes the instrument rotate with the sky. All other rotation types make the sky rotate on the instrument about the boresight.
Mount is typically used for engineering. None is used for a controlled stop and for no rotator. Physical is rarely used.
Mount rotation is the only safe way to send the rotator to instrument change position.
