Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
 (  20031215  90  cw      15:50      4.4      4.8    4.6      15 
    20040110  90  cw      11:46      1.3      2.3    3.0      20 )
    20040116  90  cw      04:45     -0.8     -0.7   -0.6      25

All data channels of the inclinometry data are OK. The resulting model is compared below with the previous two :

• Fairly substantial changes - particularly to F1 - have again occurred since the last measure, that on 10 Jan; and it's not as though the track shape has 'returned' towards that pertaining immediately following the central bearing load adjustment on 15 Dec. Further frequent monitoring is required until it 'settles'.
• The differences in (F1,F2,F3) between these two CW models are described by the rms scatters of (1.05", 0.29", 0.52") cf. (0.80", 0.80", 0.93") previously.
• The new CW model was merged with the new (CW-CCW) template to create a new hybrid track model, which was installed at HST 10:50 on 16 Jan 2004.
• Records of the symmetry and strain gauge data have been updated.
• Concerns about the impact of these changes upon pointing may be tempered by the consistently good allsky pointing this week : again last night rms scatters in (daz,el) were (1.3",1.2") from 17 logged pointings.
