    Summary
    ========

    pi0 Production : Kinematics I Part(III)

    BigBite = 43.5 degrees, BigBite current = 388.1 A
    LHRS = 20.5 degrees, LHRS momentum = 0.9600 GeV/c
    RHRS = 105.0 degrees, RHRS momentum = 0.4596 GeV/c



    00:00 Shift started with production at 4.8 uA on Loop1 6cm LH2
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


    00:03 ----> Run# 3599 ; events = 1 M

    00:24 ----> Run# 3600 ; events = 1 M

    00:43 ----> Run# 3601 ; events = 1 M

    00:57 ----> I changed the golden rootfile for replay to run 3596 for Kinematic I.
    It was run 3515 for Kinematic H.

    01:02 ----> Run# 3602 ; events = 1 M

    01:21 ----> Run# 3603 ; events = 1 M

    01:39 ----> Run# 3604 ; events = 1 M

    01:57 ----> Run# 3605 ; events = 1 M

    01:57 ----> Run# 20728 ; started Right HRS

    02:16 ----> Run# 3606 ; events = 432 K ....ROC5 rebooted itself.

    02:32 ----> Run# 3607 ; events = 778 K.....HV on S7 and S14 tripped.

    02:47 ----> HV on S7 (L7.2) and S14 ( L14.6) tripped due to beam trip.

    02:54 ----> Run# 3608 ; events = 1 M

    03:12 ----> Run# 3609 ; events = 1 M

    03:31 ----> Run# 3610 ; events = 1 M

    03:49 ----> Run# 3611 ; events = 1 M

    04:08 ----> Run# 3612 ; events = 1 M

    04:14 ----> Run# 20729 ; started Right HRS

    04:29 ----> Run# 3613 ; events = 1 M


    I noticed that the "End of Run" for entry number 233717 is incorrect in the HALOG. It has to be "End_of_Run_3613" instead of "End_of_Run_3614". The end of run information like "End of Run Comment","PRESCALE FACTORS", "EVENTS", "TIME",........., APPROXIMATE BCM CHARGES, are missing from entry number 233717.
    Run 3613 is missing in the "Runlist"


    04:48 ----> Run# 3614 ; events = 1 M

    05:07 ----> Run# 3615 ; events = 1 M

    05:25 ----> Run# 3616 ; events = 1 M

    05:44 ----> Run# 3617 ; events = 1 M

    05:45 ----> Run# 20730 ; started Right HRS

    06:08 ----> Run# 3618 ; events = 1 M

    06:27 ----> Run# 3619 ; events = 1 M

    06:46 ----> Run# 3620 ; events = 1 M

    07:05 ----> Run# 3621 ; events = 1 M

    07:23 ----> Run# 3622 ; events = 1 M

    07:42 ----> Run# 3623 ; events = 1 M

    08:01 ----> Run# 3624 ; events = 1 M


    No drift in beam enery. HALLA:P VAL = 119.38 MeV
    For the current kinematics ( I ) at the end of the owl shift: Total Charge = 0.144 C
