hillas_parameters#
- ctapipe.image.hillas_parameters(geom, image)[source]#
Compute Hillas parameters for a given shower image.
Implementation uses a PCA analogous to the implementation in src/main/java/fact/features/HillasParameters.java from fact-project/fact-tools
The recommended form is to pass only the sliced geometry and image for the pixels to be considered.
Each method gives the same result, but vary in efficiency
- Parameters:
- geom: ctapipe.instrument.CameraGeometry
Camera geometry, the cleaning mask should be applied to improve performance
- imagearray_like
Charge in each pixel, the cleaning mask should already be applied to improve performance.
- Returns:
- HillasParametersContainer:
