Comparison of SPMA Level 15 and level 16 which is corrected for Temperature. Plotted are values as deviations from a straight line:

After correction of the step over the winter vacations it becomes:

SPMB over Winter Vacations: The asterix points are as measured, the diamond points are temperature corrected. It is probably best to assume that the change over the winter gap should be zero, so the values after should be corrected by -10.6, 616.7, 887.5 microVolt respectively - as shown by the fainter curves with asterix.

The following is with polynomial fit deg6, last2: after 5th degree, before 3rd degree:

The following is with polynomial fit deg6, last3: after 5th degree, before 2rd degree:

This is with temperature effect on slope, degree before 3 and after 5, 25-Sep-2010

Without the first two points of SPMB, does not really help, but goes in the right direction we need to see what we can do for SPMB.

With the first two points of SPMB:
