BaselineSubtractedNeighborPeakWindowSum

class ctapipe.image.BaselineSubtractedNeighborPeakWindowSum(**kwargs)

Bases: ctapipe.image.extractor.NeighborPeakWindowSum

Extractor that first subtracts the baseline before summing in a window about the peak defined by the wavefroms in neighboring pixels.

Attributes Summary

baseline_end	An int trait.
baseline_start	An int trait.

Methods Summary

__call__(waveforms, telid, selected_gain_channel)

Call the relevant functions to fully extract the charge and time for the particular extractor.

Attributes Documentation

baseline_end

An int trait.

baseline_start

An int trait.

Methods Documentation

__call__(waveforms, telid, selected_gain_channel)

Call the relevant functions to fully extract the charge and time for the particular extractor.

Parameters

waveformsndarray

Waveforms stored in a numpy array of shape (n_pix, n_samples).

telidint

The telescope id. Used to obtain to correct traitlet configuration and instrument properties

selected_gain_channelndarray

The channel selected in the gain selection, per pixel. Required in some cases to calculate the correct correction for the charge extraction.

Returns

chargendarray

Charge extracted from the waveform in “waveform_units * ns” Shape: (n_pix)

peak_timendarray

Floating point pulse time in each pixel in units “ns” Shape: (n_pix)
