These are the links for the beam energy and various kinematic offsets:

1. Preliminary beam energy measurements (by Mark Jones): 4.2 GeV, 5.2 GeV, 3.8 GeV, 4.7 GeV
The energy measurements are called preliminary because the superharp information has not yet been incorporated.

2. Preliminary e+p offset determinations:
i. online single arm measurements (by Tanja Horn) 4.2 GeV, 5.2 GeV, 3.8 GeV, 4.7 GeV
To summarize, these results provided a rough online confirmation of the beam energy, HMS momentum, and HMS scattering angle. However, one or two settings have problems at 4.2 GeV, the beam energy or HMS momentum is systematically incorrect at 5.2 GeV, and a few settings have serious problems at 3.7 GeV. Happily, 4.7 GeV looks great. I don't know if these runs were all replayed with good time-to-distance maps. The reported W vs xpfp correlation in the HMS presumably means that the delta offset will be goofy for delta .neq. 0. (This is not obvious, but due to the correlation of xpfp with delta.)
When the residuals are at the 1 MeV level (as for the 4.7 GeV runs), it is also probably important to take the reponse function into account using simc since some of the fitted quantities like W and Emiss have radiative tails.
