Type:GroupStereotype:«XSDcomplexType»

This object contains a mapping of loci-to-fiber distance along the optical path for the DAS acquisition. The actual calibration points are provided in an array of DasCalibrationPoint structures consisting of three elements: a locus index, the corresponding fiber distance, and a description of the calibration type. Provide as many calibration points as necessary.

CalibrationDatum

WellboreDatumReference

Datum used as basis for measurement of calibration point distance and length.

CalibrationDescription

String2000

Free format description of the DAS calibration provided for an instance of a DAS acquisition.

CalibrationFacilityLengthUnit

String64

Unit of measurement of FacilityLength value CalibrationPoints

CalibrationIndex

NonNegativeLong

String64

Unit of measurement of OpticalPathDistance value CalibrationPoints

FacilityKind

FacilityKind

Enumeration to indicate the type of facility (well or pipeline) for this acquisition.

FacilityName

String64

Indicates which facility is being calibrated.

NumberOfCalibrationPoints

NonNegativeLong

The total number of calibration points in the array.
