calng

calng is a collection of Karabo devices to perform online processing of 2D X-ray detector data at runtime. It is the successor of the calPy package.

CalCat secrets and deployment

Correction devices each run their own calibration_client.CalibrationClient, so they need to have credentials for CalCat. They expect to be able to load these from a JSON file; by default, this will be in $KARABO/var/data/calibration-client-secrets.json (var/data is CWD of Karabo devices). The file should look something like:

{
	"base_url": "https://in.xfel.eu/test_calibration",
	"client_id": "[sort of secret]",
	"client_secret": "[actual secret]",
	"user_email": "[eh, not that secret]",
	"caldb_store_path": "/gpfs/exfel/d/cal/caldb_store"
}

For deployment, you'll want /calibration instead of /test_calibration and the caldb store as seen from ONC will be /common/cal/caldb_store.
