Muon Image Analysis#

Algorithms for detecting and characterizing muon images

Reference/API#

ctapipe.image.muon Package#

Functions#

kundu_chaudhuri_circle_fit(x, y, weights)

Fast and reliable analytical circle fitting method previously used in the H.E.S.S.

mean_squared_error(pixel_fov_lon, ...)

Calculate the weighted mean squared error for a circle.

intensity_ratio_inside_ring(pixel_fov_lon, ...)

Calculate the ratio of the photons inside a given ring with coordinates (center_fov_lon, center_fov_lat), radius and width.

ring_completeness(pixel_fov_lon, ...[, ...])

Estimate how complete a muon ring is by binning the light distribution along the ring and applying a threshold to the bin content.

ring_containment(ring, camera_radius)

Estimate the angular containment of a muon ring inside the camera's field of view.

ctapipe.image.muon.processor Module#

High level muon analysis (MuonProcessor Component)

Classes#

MuonProcessor(**kwargs)

Takes cleaned images and extracts muon rings.

ctapipe.image.muon.intensity_fitter Module#

Class for performing a HESS style 2D fit of muon images

To do:

  • Deal with astropy untis better, currently stripped and no checks made

  • unit tests

  • create container class for output

Classes#

MuonIntensityFitter(**kwargs)

Fit muon ring images with a theoretical model to estimate optical efficiency.
