[d2n-analysis-talk] end of run HV map

[Brad Sawatzky]

Hi Matt,

I believe you're correct.  The screwball map order was so that the HV
GUI would lay the HVs out in a way that matched the PMT positions in the
Hall (but that meant they were arranged in 'backwards' order in the
mapping file).

I did a quick sanity check by looking at a few of the gain calibration
runs (where HVs for PMT X were changed and explicity logged) and your
map looks good:

> # Map  BB_CER  Measured Voltage
>   1 :   pmt 10  pmt 20
>   2 :   pmt 9   pmt 19
>   3 :   pmt 8   pmt 18
>   4 :   pmt 7   pmt 17
>   5 :   pmt 6   pmt 16
>   6 :   pmt 5   pmt 15
>   7 :   pmt 4   pmt 14
>   8 :   pmt 3   pmt 13
>   9 :   pmt 2   pmt 12
>  10 :   pmt 1   pmt 11
