All data channels of all these datasets are OK. The resulting model is compared below with the current one - that taken on 28 Nov :

• Apart from the odd F3 excursion near the start, the differences are small enough that the measurements may be used merely to confirm the current track model without necessarily requiring it be updated in advance of the central bearing load ajustment today.
• The differences in (F1,F2,F3) between these two CW models are described by the rms scatters of (0.56", 0.31", 0.50") cf. (0.43", 0.43", 0.42") previously.
• Records of the symmetry and strain gauge data. have been updated.
