Status of calibrations (all)

• Calibration flowchart (Phoebe -> Jackson)
• Summary (Sean)
  • Runs with RF timing shifts: 90251, 90421, 90471, 90531
• Run summary and initial lumi estimates (Sasha)
• Status of PS (Tagger) calibration (Sasha)

- Timing offsets in TAGH/TAGM

- PS calib status

• SRC FCAL time/energy calibrations (ig)

Current status [1][2][3]

• Summary: calibrations ongoing, timeline is on the order of another month to complete.

Status of data processing (Alexander)

• completed the monitoring launch over the 2021-11 SRC/CT data set, processing the first 40 files of each run deemed physics quality, selected with the RCDB query: daq_run=='PHYSICS_SRC', beam_current > 10, event_count > 5000000, solenoid_current > 100 and collimator_diameter != 'Blocking' (aka "@is_src_production")
• The merged histogram files can be found on the work disk at: /work/halld/data_monitoring/RunPeriod-2021-11/mon_ver02/rootfiles/
• The REST files, random trigger skims and several trees are saved on cache: /cache/halld/offline_monitoring/RunPeriod-2021-11/ver02/REST/

Analysis topics (Jackson)

• Analysis topics are listed here for discussion.
• Should decide on priorities and determine dependencies on various calibrations.
• students will review physics topics with their advisors and think about interest/feasibility in determining analysis question.
• all can look at the list and comment: quick analysis vs analysis that may lead to extension or have more impact for EIC physics.
• ex: t-dep of j/psi may be significant topic, but is it feasible? do we have enough data to say anything?
