Parameters
----------
subarray: ctapipe.instrument.SubarrayDescription
Description of the subarray. Provides information about the
camera which are useful in calibration. Also required for
configuring the TelescopeParameter traitlets.
config : traitlets.loader.Config
Configuration specified by config file or cmdline arguments.
Used to set traitlet values.
Set to None if no configuration to pass.
tool : ctapipe.core.Tool or None
Tool executable that is calling this component.
Passes the correct logger to the component.
Set to None if no Tool to pass.
data_volume_reducer : ctapipe.image.reducer.DataVolumeReducer
The DataVolumeReducer to use. If None, then
NullDataVolumeReducer will be used by default, and waveforms
will not be reduced.
image_extractor : ctapipe.image.extractor.ImageExtractor
The ImageExtractor to use. If None, then NeighborPeakWindowSum
will be used by default.
