Hello Nick,

The new pictures (with full stat) are at: 
https://logbooks.jlab.org/entry/3669759 and 
https://logbooks.jlab.org/entry/3669760

The old pictures, 25 Feb cooking (with smaller stat) are at: 
https://logbooks.jlab.org/entry/3664922 and 
https://logbooks.jlab.org/entry/3664923

More old pictures, 6 Mar cooking (with large stat) are at: 
https://logbooks.jlab.org/entry/3664681 and 
https://logbooks.jlab.org/entry/3664682

I need to mention that the 6 Mar cooking with smaller stat (the standard 
10 files for monitoring) does not show this effect 
(https://logbooks.jlab.org/entry/3664971 and 
https://logbooks.jlab.org/entry/3664972), which suggests that the 
version of cooking is not the cause. It may be that a specific range of 
events in the run had S5 problems. There was a DAQ alarm during this run 
(https://logbooks.jlab.org/entry/3653567), but it was about low trigger 
rate for a bit above bit 6  and sector 5 trigger is on bit 5. The shift 
summary refers to low "Pulser"-trigger-rate alarm 
(https://logbooks.jlab.org/entry/3653533).

The online monitoring histos (https://logbooks.jlab.org/entry/3653586) do not suggest any specific issue with FTOF, HTCC, or CALs in this sector. The electron trigger rate for S5 was consistent with those of the other sectors. The number of electrons per trigger per sector does not show an obvious depletion in S5 either. The e-log does not have a record of any S5 problems for this run.
