Tdome and Tcase recalibrations
From the data, it was obvious that stations 2 and 6 had different pyg output.
It appeared that this was due to Tcase being significantly different
(0.5-1.0 C), so the calibrations were checked for all Tdomes and Tcases
in the environmental chamber (just air coupled). 8 temperatures in 5 degree
steps were used. Second-order fits to the reference were calculated since
a linear fit was not sufficient. The effect on Tdome-Tcase is shown
here.
However, the new Rlw plot shows even larger differences
between stations 2 and 6. It is clear from a plot of
Rpile that the values from these two sensors clearly were different from the
others. Obviously, we will have to check the calibrations of the Rpiles as
well.
