  3.1.5 SlopedInterpolation
  SlopedInterpolation simple linear interpolation Note 1 to entry: Compare to curve fitting using linear polynomials. See example in Table

  5.2.2 HistoricalDataConfigurationType
  historical data was collected in such a manner that it should be displayed as SlopedInterpolation (sloped line between points) or as SteppedInterpolation (vertically-connected horizontal lines between points) when RawData ... value of True indicates the stepped interpolation mode. A value of False indicates SlopedInterpolation mode. The default value is False. The Definition Variable is a vendor-specific, human readable string

  3.1.8 interpolated bounding values
  calculation using the nearest Good value Note 1 to entry:  Interpolated Bounding Values using SlopedInterpolation are calculated as follows: if a non-Bad Raw value exists at the timestamp then ... bounding value. The formula is the same as the one used for SlopedInterpolation . The StatusCode is always Uncertain_DataSubNormal . If only one non-Bad raw value can be found before

  3.1.9 simple bounding values
  calculation using the nearest value Note 1 to entry:  Simple Bounding Values using SlopedInterpolation are calculated as follows: if any Raw value exists at the timestamp then ... bounding value. The formula is the same as the one used for SlopedInterpolation in Clause 3.1.5 . If a Raw value at the timestamp is Bad the StatusCode is Bad_NoData

  5.4.3.2.2 Sloped Interpolation and Simple Bounding Values
  period before the first data point; the period between the first and second where SlopedInterpolation can be used; the period between the second and third point where SteppedInterpolation is used ... region is Uncertain if a region ends in a Bad or Uncertain value and SlopedInterpolation is used. The end point has no effect on the region if SteppedInterpolation is used

  5.4.3.2.3 Stepped Interpolation and Interpolated Bounding Values
  ignored because of the interpolated end bound but this does create Uncertain regions. If SlopedInterpolation was used the Uncertain region would start at the second point. In this case

  5.4.3.8 Total
  determined using the StatusCode Calculation (see 5.3 ). Note that this calculation always uses a SlopedInterpolation between points; Total2 uses a Stepped Attribute or SlopedInterpolation depending on the value
