| 2112 | Stopped the last run. Created file DAQSettings_2011_0404_2111.xml to bias the electrodes as if the two boards are swapped. |

Setting the bias to mimic board swapping
The script to make the plots is at here.
Comparing Fig. 1.10 with the one on 2011/03/26, the spectra variation caused by swapping the boards can be largely caused by the voltages differences between the channels.
The cuts are defined as
- cQ# = max([Q1, Q2, Q3, Q4], [], 2)==#
- cQCchisq = cQ1chisq & cQ2chisq & cQ3chisq & cQ4chisq
- cE = 50<Qsum.
