= Current Status =
* SHMS paddle study complete
* 26 degrees, setting 9 complete
* 26 degrees, setting 1 in progress
* Coffee maker working!!! (thanks Paul)! https://logbooks.jlab.org/entry/4052331
* New alarm on EDTM rate (will alarm briefly at run start, then should go away if EDTM set correctly)
* Doug H. got less annoying phone case for RC phone (now weighs less than 10 lbs.)

= Current Run Plan =
* Complete 26 degrees, setting 1
* Continue to settings 2, 3, etc.

= Notices in Effect for Shift Crew =
* Pay attention to DAQ prescale settings
* Update EDTM setting to give ~25 Hz AFTER prescale (see table near DAQ computers)
* Use good electron fraction from 50k replay to estimate how many events will be needed to get required statistics
* For settings with long runs/low rates, can run full replay (run_full_hms.sh and run_full_shms.sh)

= Current Issues =
* SHMS PRLO/PRHI thresholds might be a little on the high side (https://logbooks.jlab.org/entry/4053287), but setting lower results in very high rates in PRLO
** Maybe for SHMS, ELLO should have NO calorimeter at all (i.e., just 3/4 + Cherenkov)?
* SHMS NGC PMT1 HV set back to 1700 (https://logbooks.jlab.org/entry/4052210) we'll need more elastic data to get efficiency
* Need to analyze SHMS paddle study ASAP to determine how we'll run 8 degree data
* cermode10 in the SHMS causes significant dead time (https://logbooks.jlab.org/entry/4052716) - should we turn it off?
* Need shift workers for Tuesday, Day (then Thursday, Day)
