Changes

*'''Temperature of the SiPM board''' - we found that as the fiber runs were done repeatedly without turning off the electronics and removing the board, the photon yield decreases. Automated runs resulted in variances between 3-5%

*'''Depth of the fibers in the chimney''' - We found that differences as small as 0.5 mm can have a minor affect on the photon yields.
