Functions

kundu_chaudhuri_circle_fit(x, y, weights[, ...])	Fast and reliable analytical circle fitting method.
taubin_circle_fit(x, y, mask[, weights, ...])	Perform a Taubin circle fit with weights (optional).
kundu_chaudhuri_taubin(fov_lon, fov_lat, ...)	taubin_circle_fit with fov_lon, fov_lat, weights, mask interface with initial parameters provided by kundu_chaudhuri
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.
image_prediction(mirror_radius, hole_radius, ...)	Predict muon ring image from given parameters.
intersect_circle(mirror_radius, r, angle[, ...])	Perform line integration along a given axis in the mirror frame given an impact point on the mirror
