append()

AFPAlignDBCreate.AFPDBDict.append	(		self,
			stationID,

			shiftX = 0.0,
			shiftY = 0.0,
			shiftZ = 0.0,
			alpha = 0.0,
			beta = 0.0,
			gamma = 0.0 )

A function that overwrites one slice of the alignment constants in the dictionary. Local constants have to have layerID defined, while alignType is undefined. Global constants have to have alignType defined (tracker/RP/beam/correction) and layerID undefined.

savePayload()

A function to transform the dictionary to JSON and save it in IOV from a given run and LB; upper limits are undefined and the maximum value (until beginning of a next entry) is used.
