Pointing
The plots below show the pointing data for, respectively, RxA & RxB, restricted to the period after 16 August, when the VAX mwtsrv was replaced (and the earlier data lost):

For RxA, there seems to be a trend of the elevation residual with elevation (centre panel), while for RxB it is the azimuth residuals that show deviations at high elevations.

Thermal - i.e. analyses of the elevation residuals as functions of Receiver and antenna leg temperatures:

  FE  No.of data   fit                              Temp range
  --  ----------  ----------------------------     -----------
   A     143      del = (-1.60 +- 0.39)*T_diff     -0.8 to +1.8
                      = (-0.42 +- 0.09)*T_mean(**)   4  to  16

   B     271      del = (+1.37 +- 0.26)*T_diff     -0.8 to +1.6
                      = (-0.02 +- 0.06)*T_mean(**)   6  to  16

A confusing set of results, with no clear trends on which to base any adjustments.

            Y      45     +0.02   0.13

There are no trends of any focus residuals with elevation or temperature (range 4-16 degC for RxA, 6-16 for RxB).
