A full clockwise+counter-clockwise inclinometry run was carried out this weekend. There has been an extra week between this and our previous inclinometry run due to SCUBA2 commissioning work being carried out over the weekends. Nevertheless the results are stable with the following results.

The new data are recorded from the 3 active inclinometers and one of the two strain gauge channels. The LT trace which has had problems previously appears to running artificially low for the majority of the run. This channel was subsequently excluded from the model determination and the RT channel was used as a substitute during the analysis.

• The differences between the (CW) model derived from this run and the previous run on 11th October are shown below.

• The resulting rms scatters in the differences in (F1,F2,F3) are (0.26", 0.70", 0 22") compared to (0.44", 0.65", 0.36") previously.

• The CW-CCW profile is normal, and is used to generate a hybrid track model which was installed on the 4th November at 14:30.

• The relative loadings on the wheels continues to remain stable.
