UDATE:
The file shows three plots for each ring comparing E/p with and without TOF cuts.
The top plot shows the mean E/p vs p distribution, on this plot are a few lines. The blue lines show the placement of the momentum cut. The black and red dashed lines show the mean E/p for the ring over the selected momentum range with and without the TOF cut, respectively. Similarly, there are solid black and red lines, these show the weighted average of the bins within the blue bars (approximate percentage of the total of the 6 bins between the blue bars are as follows, starting with the 2 GeV bin: 38%, 24%, 16%, 10%, 7%, 5%. First bins dominate the sample).
The two plots below the E/p vs p plot show the E/p distribution for the ring with and without the TOF cut. These plots are where the black and red average lines from the previous plot are calculated, and also where the final E/p is taken from for calculating the final gains.

The final gains are attached as FinalRun15Gains.txt
Barring any changes to the procedure, these are the final gains and are ready to be uploaded to the database.
