Inclinometry - some 1" segment-related changes


SUMMARY
CW Inclinometry was taken during the afternoon of 31 Jan 2000. There are obvious, but small (1" amplitude), track-segment-related changes in the track model since the last run on 03 Jan 2000 .


   Datasets     HST start      mean leg temperatures   Humidity
                               start   middle   end       %
 ( inc000103 cw   04:50         0.0    -0.3    -0.4      70 )
   inc000131 cw   13:40         1.5     2.6     4.3      50

The difference between these clockwise models is shown below :

  • The differences in the (F1,F2,F3) have rms scatters of (0.65", 0.58", 0.50") cf (0.45", 0.47", 0.69") previously.

  • The new track model was installed at 17:30 HST on 20000131.

  • The symmetry remains good : see the plot .
