Serendipitous pointing during the 11 nights since the last report on 14 Sep are reported. The results of fitting the TPOINT parameters CA and IE and their errors (dS,dZ) are quoted:

(CA,IE) are to be compared with the current collimations for RxA and RxB of (0,0) and (30.6,-28.0), respectively.

The increasingly -ve values of IE may correlate with the steadily dropping nighttime temperatures:

However, no changes are contemplated to the collimations just now. (The plot was produced on 28th Sep - after a couple of nights of poor weather when the enclosure was not opened - and so the leg temperatures stabilize through the diurnal cycle).
