apply_time_average_cleaning¶

ctapipe.image.cleaning.apply_time_average_cleaning(geom, mask, image, arrival_times, picture_thresh, time_limit)[source]¶

Extract all pixels that arrived within a given timeframe with respect to the time average of the pixels on the main island.

In order to avoid removing signal pixels of large impact-parameter events, the time limit for bright pixels is doubled.

Parameters

geom: `ctapipe.instrument.CameraGeometry`: Camera geometry information
mask: array, boolean: boolean mask of clean pixels before time_delta_cleaning
image: array: pixel values
arrival_times: array: pixel timing information
picture_thresh: float: threshold above which time limit is extended twice its value
time_limit: int or float: arrival time limit w.r.t. the average time of the core pixels

Returns
