# CCB Testbeam — HRD data

HRD subset of `/projects/hep/fs10/shared/nnbar/ccb_data` from LUNARC.

## What ChatGPT should use

| Folder | What it is | Start here |
|---|---|---|
| [`sorted/`](sorted/) | **hrdSorter** waveform features (baseline, trapezoid, per-channel maxima) | [`sorted/sample/events_sample.parquet`](sorted/sample/events_sample.parquet) |
| [`parquet/`](parquet/) | **ucesb RAW** ADC tables (`HRDv_ch001`…`ch128`) | [`parquet/sample/events_sample.parquet`](parquet/sample/events_sample.parquet) |

Decode pipeline:
1. `.lmd` → [ucesb-hibeam](https://github.com/HIBEAM-NNBAR/ucesb-hibeam) → `h101` ROOT (already in the zip)
2. `h101` → [hrdSorter](https://github.com/HIBEAM-NNBAR/hrdSorter) → `sorted/` Parquet

Raw `.lmd` is kept only inside `ccb_data_hrd.zip` (binary DAQ; not ChatGPT-readable).

## Raw archive

- `ccb_data_hrd.zip` — original HRD `lmd` + `root` runs (`hrda` / `hrdb`)
