The purpose of this analysis is to calculate the relative gains in the BTOW. The slopes of each individual tower was calculated by Justin according to the W-algo wiki using Scott's method. With these slopes I then calculated the relative gains for each tower using the following formula.
The slopes in each η ring were fitted using a Gaussian and any tower that had a status not equal to 1 was not included in the fit. The optimal gain is taken to be gainoptimal = 60 / 4076. A whole slew of plots were made as well in order to QA the data. Because the status tables are different for each fill, a new gain table was calculated for each fill.
