The previous couple of times I showed the JER, it was for eTtrg = 9 - 15 GeV (the first 2 links below).  However, when it comes time to unfold the various eTtrg bins of data, I'll probably use the eTtrg = 9 - 20 GeV response matrix for all 3 bins (since it didn't seem to make a big difference; see the 3rd link below)...

So here's the JER for eTtrg = 9 - 20 GeV for various R's.
