29.4.4 DtsMeasurementTrace

ChannelSetReference

DataObjectReference

Pointer to a ChannelSet containing the comma-delimited list of mnemonics and units, and channel data representing the measurement trace.

BUSINESS RULE: The mnemonics and the units must follow a strict order.

The mnemonic list must be in this order: fiberDistance, antistokes, stokes, reverseAntiStokes, reverseStokes, rayleigh1, rayleigh2, brillouinfrequency, loss, lossRatio, cumulativeExcessLoss, frequencyQualityMeasure, measurementUncertainty, brillouinAmplitude, opticalPathTemperature, uncalibratedTemperature1, uncalibratedTemperature2

The unit list must be one of the following:

• m, mW, mW, mW, mW, mW, mW, GHz, dB/Km, dB/Km, dB, dimensionless, degC, mW, degC, DegC, degC

ft, mW, mW, mW, mW,mW, mW, GHz, dB/Km, dB/Km,dB, dimensionless, degF, mW, degF, degF, degF

Comment

String2000

A descriptive remark about the measured trace set.

FrequencyRayleigh1

FrequencyMeasure

Frequency reference for Rayleigh 1 measurement.

FrequencyRayleigh2

FrequencyMeasure

Frequency reference for Rayleigh 2 measurement.

IndexMnemonic

String64

The mnemonic of the channel in the MeasuredTraceSet that represents the index to the data (expected to be a length along the facility (e.g., wellbore, pipeline) being measured.

parentMeasurementReference

String64

Where this dtsMeasuredTraceSet was derived from a parent dtsMeasuredTraceSet (having been recalibrated for example), the parent dtsMeasuredTraceSet can be indicated by referencing its UID with this element.

PointCount

nonNegativeInteger

The number of rows in this interpreted data object. Each row or "point" represents a measurement along the fiber.

SamplingInterval

LengthMeasure

The difference in fiber distance between consecutive temperature sample points in a single temperature trace.

TraceProcessingType

TraceProcessingType

Denotes whether the trace was stored as acquired by the measurement device or recalibrated in any way.

uid

String64

Unique identifier of this object.

From: DtsMeasurementTrace.
