 == Preparation for the fall 2016 run ==
-- Naomi and Beni are looking at the latest CDC data. Cody: there's an issue with one module in the CDC4 crate.
+- Naomi: in the last days the temperatures in the CDC have drifted from their standard values. Nick prepared a plot attached above demonstrating this. Will discuss it with Tim. The noise in the CDC turned out to be a result of using different triggers: the noise disappeared once Naomi used the correct trigger type (code provided by Beni).
 - Lubomir is analyzing the FDC data from the latest run 21050. Sasha excluded FDC6 and FDC11 for this run due to problems with them, but Cody tested them with his own code and they are fine, suspect software problem.
