clas12-config

The standard run-group configuration files for GEMC, COATJAVA, chef workflow configurations, etc.

Standard gcard/yaml combinations for the different data sets and data-processing passes are listed in setup.json.

Notes

• GEMC versions prior to 5.4 do not fully support binary magnetic field maps and CCDB for RF configuration.
• COATJAVA versions prior to 10.0.7 do not support AI- denoising or track-finding.
