MuonIntensityFitter#
- class ctapipe.image.MuonIntensityFitter(**kwargs: Any)[source]#
Bases:
TelescopeComponent
Fit muon ring images with a theoretical model to estimate optical efficiency.
Function for producing the expected image for a given set of trial muon parameters without using astropy units but expecting the input to be in the correct ones.
The image prediction function is currently modeled after [CCdNT13].
For more information, also see [GFM+19].
Attributes Summary
