Analysis tasks
General guidance
- Don't wait for meetings - reach out for help if stuck
- Use the elog: https://hallcweb.jlab.org/elogs/XEM2/
Initial post-run tasks
- Finish Casey's thesis (Casey) (DONE)
- Wrestle snake of Nadia's choice(PENDING)
- Clone online replay - create pass 1 repository --> all updates should go into this repository (COMPLETE)
- Verify standard.kinematics for HMS and SHMS
- Check for target mass, duplicates, missing runs, correct energy (Casey) (COMPLETE)
- Check angle pictures in CODA file (Penny and Nadia) (COMPLETE)
- Angle pictures have been created and added to /mss/ (COMPLETE)
- Correct angle values have been updated in standard.kinematics (Abhyuday) (COMPLETE)
- Verify magnet settings (Burcu) (HMS COMPLETE) (SHMS COMPLETE)
- Check run lists against standard.kinematics and run sheets (Nadia - SHMS, Abhyuday - HMS) (HMS done, SHMS ongoing)
- Small replay update
- Set angle and momentum offsets to zero (Dave G) (COMPLETE) - already zero when I looked
- Add/verify that momenta and angles used in the analysis are written to report files (including any offsets) (Cameron) (COMPLETE)
- Add pointing offsets used in hcana to report files (they're hard-wired!). (Casey) (COMPLETE)
- Add more stuff to epics tree (helium target temperatures and pressures) (Dave G - def files) (COMPLETE): Note: target position only valid for runs starting from first helium running
- Add target encoder to T and scaler tree (Dave G) (COMPLETE) Not easy to add to scaler tree (needs new code?). Added to T tree, but only valid after switch to He targets
- Verify correct BPM calibration in replay (Dave G) (COMPLETE)
- Use high-momentum HMS matrix element files where appropriate (Shujie) (PENDING) Useful optics info
- Check fast raster calibrations have right sign (Tyler) (COMPLETE (it didn't))
- Fix rootlogon.C to point to correct directory (Cameron) (COMPLETE)
- Fix hms_shared.h bug that causes bcm's to not be loaded correctly (Cameron) (COMPLETE)
