Detailed Description

Detector channel-to-position mapping for the ePIC dRICH beam test.

Provides a full chain of lookups from raw ALCOR readout identifiers (device, chip, EO channel) to physical (x, y) hit coordinates on the SiPM plane, and exposes pre-built caches for performance-critical loops.

Coordinate chain

(device, chip) ──► (PDU, matrix)   [loaded from calibration file]
      EO channel ──► DO channel     [static look-up table per matrix]
 (DO channel, matrix) ──► (col, row) inside the PDU 16×16 grid
      (PDU, col, row) ──► (x, y) mm  [PDU origin + optional 180° rotation]

Todo:

Add a method to generate a full-coverage map (Cartesian and R-φ).

Profile cache benefit vs. on-the-fly computation.
