Below are the "resolutions," sigma(x) = (xMC - xReco) / xMC, for the track phi, eta, and pT as calculated from the Run 9 dijet embedding sample (RFF configuration).  The large values of sigma(phi) and sigma(eta) are due to situations where phi, eta ~ 0.  Since we only consider tracks with pTreco > 0.2, the denominator is always finite.

Note: the "no." of tracks along the y- and z-axes is weighted by the fudge factors for the corresponding partonic pT bin...

Edit [04.16.2016]: the x-axes of the 2D distributions were incorrect.  The incorrect plots have been replaced with their correct counterparts.
