fc_find_acceptance_interval_poisson

gammapy.stats.fc_find_acceptance_interval_poisson(mu, background, x_bins, alpha)

Analytical acceptance interval for Poisson process with background.

\[\int_{x_{min}}^{x_{max}} P(x|mu)\mathrm{d}x = alpha\]

For more information see documentation.

Parameters:

mu : float

Mean of the signal

background : float

Mean of the background

x_bins : array-like

Bins in x

alpha : float

Desired confidence level

Returns:

(x_min, x_max) : tuple of floats

Acceptance interval
