neighbor_average_maximum

ctapipe.image.extractor.neighbor_average_maximum(waveforms, neighbors_indices, neighbors_indptr, local_weight, broken_pixels)

Obtain the average waveform built from the neighbors of each pixel

Parameters:

waveformsndarray

Waveforms stored in a numpy array. Shape: (n_channels, n_pix, n_samples)

neighbors_indicesndarray

indices of a scipy csr sparse matrix of neighbors, i.e. ctapipe.instrument.CameraGeometry.neighbor_matrix_sparse.indices.

neighbors_indptrndarray

indptr of a scipy csr sparse matrix of neighbors, i.e. ctapipe.instrument.CameraGeometry.neighbor_matrix_sparse.indptr.

local_weightint

Weight of the local pixel (0: peak from neighbors only, 1: local pixel counts as much as any neighbor)

broken_pixelsndarray

Mask of broken pixels. Broken pixels are ignored in the sum over the neighbors. Shape: (n_channels, n_pix)

Returns:

average_wfndarray

Average of neighbor waveforms for each pixel. Shape: (n_channels, n_pix)
