That is correct. I have not yet implemented the calibration data in
the plots. I wanted to have a public record of the raw data, and I
am still working on understanding the calibration and how it relates
to the differences in the map. This is the first week of classes,
so I have been slowed down a bit, but will get there soon.<br>

<div>Hi All,<br>
<br>
As Dan has indicated, it looks like probe 4 is consistently
different (approx 5 gauss) from the other probes. After the 2nd
configuration run we will recheck our calibration. This will
involve setting up the first configuration again to get the
probes in the "steady" field region.<br>
<br>
<br>
In addition, it appears that the calibration data was not added
for each Hall probe (as they all consistently read over the NMR)
in the plots. Is this true?<br>
