As you can see from the graph, there is a large discrepancy between the different tests of the same fiber. This could be caused by several things, such as
As you can see from the graph, there is a large discrepancy between the different tests of the contorl fiber. This could be caused by several things, such as

We redesigned the "thermal finger" for holding the two different SiPMs. The designs are seen below. The purpose for this is so that the SiPMs can be changed out easily and that we can ensure that the device is in the same position every time.
