910 08/06/2012 Laura 9650 (BLAST) -1.8 Prototype Testing (Cosmic) 9cm Aerogel run in the dark-box. Using separate HV sources. Tracker still shows two patches of events above the pedestal. Notice large error on fit of signal peak. Npe~9.4

912 08/07/2012 Laura 9650 (BLAST) -1.8 Prototype Testing (Cosmic) 7cm Aerogel run in the dark-box. Using separate HV sources. Overnight run. Tracker: about 3 patches of signal above pedestal. Signal: mostly one signal peak (second very small patch at ~400 seems more like trailing peak). Npe~6.8

913 08/08/2012 Laura 9650 (BLAST) -1.8 Prototype Testing (Cosmic) 6cm Aerogel run in the dark-box. Using separate HV sources. 6 hour run. Seems to be too few data points and therefore a bad fit to the signal peak. Run 914 is the same but for a longer time.

914 08/06/2012 Laura 9650 (BLAST) -1.8 Prototype Testing (Cosmic) 6cm Aerogel run in the dark-box. Using separate HV sources. Tracker: very small patch of signals between 400 and 600. Npe~6

914 (part 2) 08/06/2012 Laura 9650 (BLAST) -1.8 Prototype Testing (Cosmic) This is the constant DC signal that is used to track any movement in the gate for the prototype. Notice the small patch of events above the main pedestal.
