... The main purpose of this task is the correction for attitude drifts using the dispersion coordinate system. The dispersion coordinates are defined based on the position and on the orientation of the RGA, and have two components: the dispersion angle BETA and the cross dispersion angle XDSP . ... This is called reference attitude and basically means that this is the on-axis sky position to which the telescope points after the attitude drift correction was performed. ...
