Inclinometry was performed as follows:

Data is recorded from the 3 active inclinometers and one of the two strain gauge channels. The LT trace is again abnormally low, so the RT data is used to correct LX & LY.

• The differences between the (CW) model derived from these new data and the previous model of 12 Apr are shown below:

• There is essentially no change in the track profile since last time. The rms scatter in the differences in (F1,F2,F3) are (0.43", 0.29", 0.22") cf (0.32", 0.30", 0.50") previously.

• The CW-CCW data are of the 'small amplitude' variety, and were used to generate a hybrid track model which was installed at ~HST 09:50 on 29 April 2008.

  The symmetry and the strain gauge data are OK.
