Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
  ( 20050403  90  cw      09:47      4.1      5.2    6.2      17 )
    20050417  90  cw      10:08      4.5      5.7    6.7      60

All inclinometry and temperature data channels look; Ch13 - the #1 strain gauge - is still not functional.

The difference between the CW model resulting from these new data and the previous one of 19 Mar is shown below:

• There are some broad (10deg wide) features, of low amplitude particularly in the F1 difference : at azimuths 145, 230, 250, 280, 330. Not much to get alarmed about right now, but worth monitoring.
• The differences in (F1,F2,F3) are then described by rms scatters of (0.47", 0.17", 0.25") c.f. (0.31", 0.15", 0.33") previously.

• The new CW model was merged with the (CW-CCW) template to create a new hybrid track model, which was installed at HST 17:10 on 18 April 2005.
• The symmetry (defined here) fell wrt last time, but remains elevated & stable wrt previous times. The wheel loads - as judged from strain gauge No.2 only - are OK.
