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.
