Some footnotes:
In calculating the total charge, "BCM u3" reading was used from the "End of Run" info.
Each of the following runs has two "End of run" info:
2627, 2754, 2779 and 3064.
During analysis, the analyzer crashes for the runs 2748 [after 148k events], 2963 [after 154k events] and 2980 [after 157k events] while the run 3220 has ThaSlotData-problem between the events 136 to 151 k.
Most of the runs from 1882 to 1916 do not have Coincident timing info [CT.ct_2by1 or CT.ct_1by2]. Many of them are junk.
Runs 1917 to 1967 do not have CT.ct_2by1. (but they have CT.ct_1by2).
Total charge of all the 4-pass carbon runs is about 59 C.
The numbers in the kinematics table are all "central" values.
Production data were taken in constant (q,&omega) kinematics by fixing electron kinematics. The recoil momenutm was varied by detecting the ejected proton at different angles with respect to q.
