Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
  ( 20040919  90  cw      10:28      7.7      8.5    9.3      20 )
    20041003  90  cw      10:17      5.5      6.7    7.1      26

The resulting CW model is compared below with the current one - that taken on 19 Sep :

• The +14" spike in F2 at 10 The differences in (F1,F2,F3) between these two CW models are described by the rms scatters of (0.29", -----, 0.26") cf. (0.26", 0.18", 0.33") previously.
• Because of the insignificant change in the derived track model - and because of the Ch1 fault - no update using these data is performed.
• Records of the symmetry and strain gauge data have been updated; all looks fine.
