... The OM Tracking History Files give only relative displacements as attitude information, and how this will be translated into absolute RA and Dec is still uncertain. ... It is thought, at the moment, that the AHF may only have a very few number of entries in it, and as such, atthkgen may seem not well suited to such a situation. Note though that it is envisaged that the movement offset threshold at which new AHF entries will be input may be reduced from 2.5 arcsec to 0.5 arcsec. ...
