The new data are recorded from the 3 active inclinometers and one of the two strain gauge channels. The LT trace which has had issues previously suffered a problem during the middle of the run. This channel was subseuently 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 15th June are shown below.

• The resulting rms scatters in the differences in (F1,F2,F3) for the left hand plot are (0.58", 0.52", 0.38") compared to (0.34", 0.28", 0.42") last time.

• The CW-CCW profile is normal, and is used to generate a hybrid track model which was installed on the 29th June at 14:00.

  
  Strain Data
  At first glace the strain gauge readings appear to be holding steady, but closer analysis (see strain gauge data) reveals another drop in loadings particularly wheels 1 and 4. This potential trend will be monitored more closely.

  

  20090702 update

  This morning we ran a adjusted cw inclinometry run with the sole purpose of gathering strain gauge data. Data was collected only for those azimuths where a wheel passes over the fixed strain gauge. The drop in the loadings (relative to wheel 3) becomes more apparent with wheels 4 and 3 looking particularly reduced.
