... 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. ... V2 = X sin(A) - Y cos(A) . V3 = X cos(A) + Y sin(A) . ...

11. ASTROMET/COMPUTE
... It uses the transformation parameters computed by the command ASTROMET/TRANSFORM . ... ASTROMET/COMPUTE computes the RA,Dec coordinates from X,Y coordinates directly from the transformation parameters, while it obtains X,Y from the RA,Dec ones in an iterative manner. Also note that the equinox of the computed coordinates is the same as the standard star catalogue (which is NOT necessarily the same as its epoch) and is 2000.0 in case the PPM catalogue is used. ...
