• Sequence [1..1]
  from type structures:ObjectType
  from subst. group structures:ObjectAugmentationPoint
  structures:ObjectAugmentationPointAbstract [0..*]An augmentation point for ObjectType
  from type cbrn:RemarksComplexObjectType
  cbrn:RemarkText [0..*]A placeholder for comments intended to help the consumer of the data to understand better the information encapsulated by the parent element.

  cbrn:RemarksComplexObjectAugmentationPointAbstract [0..*]An augmentation point for cbrn:RemarksComplexObjectType.
  1. Choice [0..*]
     from subst. group cbrn:CoefficientOrBoundaryValuesChoiceAbstract
     cbrn:CoefficientValueListA list of values of the coefficients of a second-order polynomial describing the energy calibration in which the energies are expressed in keV.
     cbrn:EnergyBoundaryValueListA list of energy values that indicate the energy of the start of each channel in a spectrum and the end of the last channel of the spectrum; the energies shall appear in the list in increasing order.
  2. cbrn:EnergyValueList [0..1]A list of energy values, in units of keV; the energies shall appear in the list in strictly increasing order. This element appears paired with an element that provides a corresponding list of other values, such as the EnergyDeviationValues, FWHMValues, or EfficiencyValues elements. The number and order of corresponding values in the pair of lists must match.
  3. cbrn:EnergyDeviationValueList [0..1]A list of values providing the differences in the energies predicted by an energy calibration coefficients equation and the true energies. EPredicted = T0 + T1*C + T2*C2 EDeviation = f(EPredicted) EActual = EPredicted + EDeviation Where Tn are the coefficients from the CoefficientValues element data, C is the channel position (the first channel starts at "0.0"), EPredicted is the predicted energy (in keV) at channel C, EDeviation is the energy deviation value (in keV) from interpolation of the EnergyValues and EnergyDeviationValues data, and EActual is the final corrected energy at channel C.
  4. cbrn:CalibrationDateTime [0..1]A date and time at which a calibration was put into service.
  from subst. group cbrn:EnergyCalibrationAugmentationPoint
  cbrn:EnergyCalibrationAugmentationPointAbstract [0..*]An augmentation point for cbrn:EnergyCalibrationType.
