[d2n-analysis-talk] Tracking-Cut Performance for Replay Round 2

[Diana Parno]

Hi folks,

I only have one plot for today's meeting, and Matt's already seen it,  
so I thought I might just send it out over email. This shows the  
tracking efficiency for the 5.9-GeV dataset for both rounds of replay,  
reflecting changes that Matt made to the MWDC calibration. As you can  
see, these changes had a big effect for several early runs, but for  
most of the run period the tracking was already about as good as we  
were going to get.

For comparison, I've also attached the same plot for the 4.7-GeV  
dataset. Here the tracking efficiency was pretty flat, but was  
typically lower (~15.5%) than for the 5.9-GeV data.

Best,
Diana
