There is a pointing model, accurate to about 2arcmin, whose correction values are stored in the file `TJ8919'. (8) Between measured pointing offsets the values are interpolated. There are also separate pointing models which are optimized for the northern and southern sky. The last pointing observation documented is in NFRA note 290.
The telescope steering software can keep the telescope on the demanded position to within 0.6arcmin, but of course pointing is made worse by very high winds (above Beaufort scale 7).
