[Halld-tagger] Analysis of tagger field map at 0.75 T added

[Timothy Whitlatch]

Hi All, 

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. 


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?
