The Minimum2 Aggregate defined in Table 26 retrieves the minimum Good value for each interval as defined for Minimum except that Simple Bounding Values are included. The Simple Bounding Values for the interval are found according to the definition of Simple Bounding Values (see 3.1.9). Any Bad values are ignored in the computation. The Aggregate StatusCode will be determined using the StatusCode Calculation (see 5.3) for time based Aggregates. If a bounding value is returned then the status will indicate, Raw, Calculated or Interpolated.

If TreatUncertainAsBad is false and an Uncertain raw value is the minimum then that Uncertain value is used. Uncertain values are ignored otherwise.

If sloped interpolation is used and the End bound is the minimum value then End bound is used as the Minimum with the timestamp set to the startTime of the interval. The End bound is ignored in all other cases.

Before Start of Data

After End of Data

Bad_NoData

No Start Bound

Treat the beginning value as Bad_NoData and compute the Aggregate

No End Bound

Treat the ending value as Bad_NoData and compute the Aggregate

Bound Bad

Use as value and compute the Aggregate as defined

Bound Uncertain

Use as value and compute the Aggregate as defined
