Estimate of run time for thcm=135 phi=180
I set up a paw_kumac/mm_check.kumac to estimate the time
needed for a kinematic point.
The results for run 2099 are
Run = 2099 thcm=thcm-135
tc_cor peak sum=4364 back sum=244 ratio peak/back =17.8852
Sum of missing mass = 4333 , 543.85 events/mC
Sum of missing mass minus back = 4109 , 515.735 events/mC
Sum of missing mass cut on Q2,W = 914 , 114.719 events/mC
Scale by raw/back
missing mass cut on Q2,W = 108.788 events/mC
Need 2100000 events in tight cut, so 19.3036 C needed
At 65 uA the time would be 82.494 hours
At this point we already had 2.68C with the large collimator
which gave at 75 events/ mC which is equivalent to about
1.9C already. So we need 17.4C more at the open collimoators.
This would be 77 hours at 65uA. So if things go well maybe we will
change on Sunday.
I will write up something more extensive for the other kinematics.
