compute_lima_on_off_image¶

gammapy.detect.compute_lima_on_off_image(n_on, n_off, a_on, a_off, kernel)[source]¶

Compute Li & Ma significance and flux images for on-off observations.

Parameters:	n_on : `WcsNDMap` Counts image n_off : `WcsNDMap` Off counts image a_on : `WcsNDMap` Relative background efficiency in the on region a_off : `WcsNDMap` Relative background efficiency in the off region kernel : `astropy.convolution.Kernel2D` Convolution kernel
Returns:	images : dict Dictionary containing result maps Keys are: significance, n_on, background, excess, alpha
