Poisson Distribution 10/06/08SJK 02:06, 1 November 2008 (EDT)
I collected data for dwell times of 2 s and 4 s.
The data for a 4 s dwell time was unusual in that initially, there were some seemingly abnormal data indicating a much higher count rate than was to be expected. In addition, the computer screen displayed some graphical anomalies, such as blurring letters and a distorted graph. However, this acquisition pass still produced useful data, on which I will conduct some extra analysis. I do not know the causes of either the anomalous data or the graphical problems, but they should not pose a problem for data analysis.
I also collected some data for a dwell time of 8 s. I was not able to collect a full set of data for an 8 s dwell time due to time constraints, however, I did collect a set large enough to perforrm analysis. I encountered more graphical anomalies during data collection, as well as some unusual data close to the end of data collection. I will perform some extra analysis on that data which I was able to collect, similar to what I will do for the 4 s dwell time data.
After the anomalous readings subsided, Boleszek wanted to move the PMT so that he could continue his experiment in a clear area; I permitted him to do so. The effect on final data collection appeared to be negligible.
