Wednesday+November+28th,+2012

Today I opened the file containing the full 100k event excel file. I looked over the file and saw that like the one I did Monday, it was only partially filled out. I began my work inserting new columns and then putting in the equations for each column. I copy and pasted the formulas into the excel file. This took quite a long time.

This image is the added columns into excel. I needed to add these columns because the file was not complete, as I said before. I used the copy and paste technique to get the correct formulas into excel. I copy and pasted because if a single variable of the formula had been altered slightly, the solution to the problem would be wrong. After inputting at the correct formulas, I dragged all the columns down, all 100k events. After selecting the whole 100k events, it took several minutes for all of the event equations to be answered and load up properly. I plan on looking through the events to find possible evidence for cosmic rays.

Once again in my excel file solutions, I encountered these anomalies in the file. As I said in Monday November 26th log entry, this is probably a problem that cannot be solved due to an invalid variable of some kind. I plan on asking John or Dr. L about how to fix these equations, if there is any possible way to do it.

I also did the equations involving ßx ßy ßz ß and y. These equations were essential in getting all of the equations done correctly. If I had decided to omit these from my excel work, I would not have gotten the correct solutions to the equations.

For more information on what I did, read my logbook entry from Monday November 26th, 2012. This logbook paired with the logbook entry from Monday should give a fairly good description of what I have done on these excel file graphs. Next time I am in the lab, I plan on talking with John and other members of the group on how to identify cosmic rays through looking at the numbers in such a large group of recorded events.

The work I did today was done outside of the Quarknet facility.
