This report covers those dates for which the model installed on 8th July was in use. This model was replaced on the 21st August when SCUBA2 going back on the telescoped demanded a new determination of the model

Without any adjustment for nightly collimation differences, they behave as follows:

      Dataset       FE     No.    CA  ± dS       IE  ±  dZ
                                    (daz)          (del)
   090709-090820    A     359    +2.3 ±  2.3    -4.2 ± 3.3 

   090709-090820    H     193   +19.5 ±  2.6   +35.2 ± 3.6
 

These are displayed below; RxA on the left and HARP on the right:

The excess of RxA pointings over HARP implies the poor weather we had over this period. This has contributed to higher than nominal rms values. The trend with elevation for RxA was also observed to a degree in the previous report and is puzzling as this trend has now been observed for 2 different pointing models suggesting it may not be due to an errant term in a particular model.
