A C++/ROOT framework for processing and analysing ePIC dRICH beam-test data, covering the full chain from raw ALCOR readout to reconstructed Cherenkov rings.

Data levels

Level	Class	Description
Raw	`alcor_data`	Direct ALCOR decoder output
Light	`alcor_lightdata`	Time-clustered, trigger-tagged hits
Reco	`alcor_recodata`	Position-mapped reconstructed hits
Track	`alcor_recotrackdata`	Track-matched hits from ALTAI telescope

Key components

mapping — Channel-to-position lookup chain (device/chip/EO → x,y mm)
alcor_data_streamer — Sequential ROOT TTree reader
run_info — TOML-based run metadata and run-list database
readout_config_list — Readout role assignment and conflict resolution
