Although the conversion of telescope offsets from the FOS ( x,y ) reference frame to the telescope (V2,V3) reference frame is provided in the FOS paper products for all acquisition slews, you may occasionally need to calculate this rotation for other purposes. As noted in Chapter 29, the FOS ( x.y ) coordinate system is defined so that the x -axis is parallel to the diode array and the y -axis is perpendicular to the diode array. ...
