 - **aggregationType**: Specifies the type of aggregation (see [here](https://github.psi.ch/sf_daq/ch.psi.daq.domain/blob/master/src/main/java/ch/psi/daq/domain/query/operation/AggregationType.java)). The default type is *value* aggregation (e.g., sum([1,2,3])=6). Alternatively, it is possible to define *index* aggregation for multiple arrays in combination with binning (e.g., sum([1,2,3], [3,2,1]) = [4,4,4]).
-- **aggregations**: Array of requested aggregations (see [here](https://github.psi.ch/sf_daq/ch.psi.daq.domain/blob/master/src/main/java/ch/psi/daq/domain/query/operation/Aggregation.java) for possible values). These values will be added to the *data* array response.

+- **extrema**: Array of requested extrema (see [here](https://github.psi.ch/sf_daq/ch.psi.daq.domain/blob/master/src/main/java/ch/psi/daq/domain/query/operation/Extrema.java) for possible values). These values will be added to the *data* array response. 
 - **nrOfBins**: Activates data binning. Specifies the number of bins the pulse/time range should be divided into.
 - **durationPerBin**: Activates data binning. Specifies the duration per bin for time-range queries (using duration makes this binning strategy consistent between channel with different update frequencies). The duration is defined as a [ISO-8601](https://en.wikipedia.org/wiki/ISO_8601#Durations) duration (e.g., `PT1H` for 1 hour, `PT2S` for 2 seconds, `PT0.05S` for 50 milliseconds  etc.). The resolution is in milliseconds and thus the minimal duration is 1 millisecond. 
 - **pulsesPerBin**: Activates data binning. Specifies the number of pulses per bin for pulse-range queries (using number of pulses makes this binning strategy consistent between channel with different update frequencies).
