0934 Filled N2 cold trap.
1454 Stop the DAQ after 07110405_1325. Flash the detector. The series 07110405_1456 has too few events even to make a filterfile.
1954 Stop flashing detector.
Filled N2 cold trap.

Scipt

The cuts are defined as

  • cQ# = max([Q1, Q2, Q3, Q4], [], 2)==#
  • cQCchisq = cQ1chisq & cQ2chisq & cQ3chisq & cQ4chisq
  • cE1 = 15 < Q1;
  • cE2 = 15 < Q2;
  • cE3 = 10 < Q3;
  • cE4 = 20 < Q4;
  • cE = 50 < Qsum.

Comments:

  • Not so many events on Q1 and Q3. The change is not unexpected compared with uncalibrated -6V data.
  • Cross talk is strange.
