select_pixels(waveforms, telid=None, selected_gain_channel=None)[source]¶

Abstract method to be defined by a DataVolumeReducer subclass. Call the relevant functions for the required pixel selection.

Parameters

waveforms: ndarray: Waveforms stored in a numpy array of shape (n_pix, n_samples).
telid: int: The telescope id. Required for the ‘image_extractor’ and ‘camera.geometry’ in ‘TailCutsDataVolumeReducer’.
selected_gain_channel: ndarray: The channel selected in the gain selection, per pixel. Required for the ‘image_extractor’ in ‘TailCutsDataVolumeReducer’.
