- An optional attribute "selectNumberOfLowestMin" may be defined. The value attribute defines the number of lowest minimum values which will be written to the output timeseries.
- The periodTransformation may be applied to this transformation (see Configuration example 2 below).
Output
Timeseries containing the selection of minimum values.

In this example:
- For each hydrologic year, the three lowest minimum values are returned by the output time series.
