[Experiment] mfx102101026 (Ferricyanide XES) - MFX

[lg345]

Static and droplet Fe Kα/Kβ XES for the ferricyanide/ferrocyanide redox series.

Branch: https://github.com/lg345/XSpect/tree/mfx102101026
(merged into feature/yaml-pipeline-architecture)

Analysis delivered

• Static XES pipeline (experiments/mfx102101026/mfx102101026_static_xes.yaml) on epix100_0 with import-time row_range crop, hitfinding min_sum, ferricyanide ROIs, von Hamos energy axes.
• Notebooks: visualization, aggregate, ferricyanide (Fe³⁺) reference builder, run-9 baseline/speciation, non-expert speciation_simple (with eLog beamline-summary posting), and droplet visualization.
• Droplet-reconstructed XES workflow (mfx102101026_droplet_recon_xes.yaml) using the native droplet_reconstruction step.
• XSpect engine additions used here: import-time detector row_range crop (+ auto ROI offset translation), hitfinding min_sum, logging/enable_logging.

Tracked issues for this experiment:

• Enable droplet2Photons reconstruction for mfx102101026 (LUTE template fix + validation) #97 — Enable droplet2Photons reconstruction (LUTE template fix + validation) — BLOCKER for photon-counted imaging
• List-mode per-shot spectra: rotation + gap correction directly on droplet sparse arrays (no full-image reconstruction) #96 — List-mode per-shot spectra: rotation + gap correction on sparse arrays
• Droplet Analysis Rotations #70 — Droplet Analysis Rotations
• Hitfinding does not play well with updates to droplet analysis #55 — Hitfinding does not play well with updates to droplet analysis
• Reconstruct shot-by-shot detector images from droplets. #45 — Reconstruct shot-by-shot detector images from droplets

Operational notes

• ePix100 common-mode gotcha resolved (do not pass cmpars tuple → psana 3D-index crash on 2D frames).
• Runs 4/5/8 had no beam (excluded); run 9 first 30 Hz run.
