November 7
I began work today by re-inserting the missing photos into last week's log and briefly editing their descriptions. Then, I read through many of the graphs of my group members (Jason and Jeremiah in particular). I added a comment to Jeremiah's just before Alex began commenting on my graphs. I then focused my attention to further analyzing my graphs with the help of Alex's comments. We discussed (verbally and through the wiki) the trend of my pz vs. eta graph (whether it is linear or sinusoidal), and in doing so, we discovered an interesting aspect: the domain of the x axis, reflecting eta, appeared to be between the value of -e and e (around -2.7 to 2.7). Then, Dr. L provided us with an excel file full of data in order to begin our next task (excel file of 1000 dimuon events). Our task is to create a new column of (E1+E2)/M, sort the data, and isolate cosmic rays based on the ratio. We added the new column of data [(E1+E2)/M] and sorted the data by this value, smallest to largest.
