Review staffing for shifts - still light on Saturday shift 2
Friday Saturday Shift 1 (6p-1a) Philip, Dionisio, Kaz, Lorenzo, Alex (remote), Xavier Bhavna, Philip, Julian, Bojan, Xavier Shift 2 (11p-6a) Bhavna, Zongde, Julian, Bojan, Dionisio (tentative), Alex (remote) Kaz, Zongde, Alex (remote)
- Analysis scripts
- need runs at MFX/RIX to test scripts properly, Alex to take that data
- Some concern about very high noise in the HR, based on what Philiph/Zongde have seen in single photon data
- What we need to do and check during bedtime
- Pedestal scan:
- Check pedestal noise
- Check temperature stability – nominal temp and stability
- Linearity scan:
- Check switching point
- Check residuals
- Gain ratio between high/medium/low
- Flat field:
- SNR for single photon
- Pedestal scan:
- Analysis bookkeeping:
- Maybe shared slides to throw plots into and keep everyone update in realtime and to declutter slack
- If there's enough personnel on a shift, have someone take notes of discussions of what we're seeing

Data-taking scripts (all same as before?)
- seq_epixhr --rate RATE --daq subharmonic_division --tgt TGT
- e.g. seq_epixhr --rate 5160 --daq 2 --tgt 0.834e-3
- This would be runrate=5160, daqrate=5160/2
- --tgt may not be needed.
- e.g. seq_epixhr --rate 5160 --daq 2 --tgt 0.834e-3
- epixhr_timing_scan --linear START STOP STEPSIZE --events EVT_PER_STEP --record
- e.g. pixhr_timing_scan --linear 2000 40000 1000 --events 1000 --record 1
- start_ns default location same as before? (24000?)
- epixhr_pedestal_scan --record 1 --event 8000 (start with FH)
