Following an increase in frequency of track model updates, a full cw/ccw inclinometry run was performed on May 30th.

The new data are recorded from the 3 active inclinometers and one of the two strain gauge channels.

• The differences between the (CW) model derived from this run and the previous run on 25th May are shown below.

• The resulting rms scatters in the differences in (F1,F2,F3) for the left hand plot are (0.25", 0.41", 0.43") compared to (0.31", 0.22", 0.94") last time.

• The CW-CCW profile is normal, and is used to generate a hybrid track model which was installed on the 1st June at 11:00.

  
  Strain Data
  The strain gauge readings since the central beating adjustment have shown the loads on the wheels remaining approximately constant thus far (see strain gauge data), we will continue to monitor this weekly however.
