During my presentation to JetCorr on May 29th, 2018 the profile of the Response Matrix shown raised some eyebrows (see slide 12 in the link below).  It turned out I had drawn it with the errors bars being actual errors rather than the standard deviation.  Below is the response matrix with the correct profile.

The error bars on the jet reconstruction efficiency (slide 11 in the same link) also struck some as off. I double-checked to make sure ROOT was calculating the errors as anticipated, and it is.
