13.62 degrees

I noticed a hardcoded

  aRotation.rotateY(-13.62*CLHEP::degree);

in Offline/GeneralUtilities/src/OrientationResolver.cc
In a geometry description file Offline/Mu2eG4/geom/protonBeamDump_v03.txt
we have

double         protonBeamDump.coreRotY = 13.72; // degrees

I am wondering if these two angles are different because one of them did not get updated.
Or maybe they are not supposed to be identical and the current code is fine.

An update: the as-built drawings docdb-11669, C-SET_6-10-2-AB, show a 76.37850 angle between the walls of the TS hall and M4 beamline. This matches the 13.62 degree (90 - 76.37850 = 13.62150). OTOH the 13.72 degree angle is not explicit in the drawings.
