Description

Raw Data Decoder

Classes of the Raw Data Decoder that convert the raw data collected by the BM@N DAQ into DIGI files with the detector digits for the reconstruction.

The decoding is started by macro/run/run_raw_bmn.C (see macro/run) and consists of two steps managed by BmnRawDataDecoder:

Conversion: BmnRawSource reads the raw DAQ file (*.data, also compressed, see compression) and writes the data of the readout electronics (ADC, TDC, TQDC, MSC, synchronization, trigger and T0 data, see base/raw) and the spill metadata to an intermediate ROOT file.
Decoding: BmnDecoder converts the electronics data into the detector digits using the channel mappings and calibrations of the period, calculates the pedestals and noisy channels of the strip detectors and writes the DIGI file with the event headers.

The channel mappings and calibration files are taken from the input and parameters directories, and the decoder settings from config/bmnconf.json.
