30 degrees
Time Start Time Stop Time elapsed (min.) Thresholds on both Scintillators Singles Count (on top) Coinc. Counts Coinc. per minute Angle measure
5:13 pm on 8/24 11:13 am on 8/25 1080 min 225 109718 2668 2.62 0 degrees
11:37 am on 8/25 1:23 pm on 8/27 2975 min 225 398313 2437 .819 45 degrees

It was decided on Saturday to not change the threshold but to proceed right to changing angles. For reference, 0 degrees is vertical with the top scintillator facing up.

Today we are beginning to measure with the telescope at 30 degrees. This week, we are planning to map out all the points at 15 degree intervals from 0 to 90 degrees.
