GaussianBand2D

class gammapy.background.GaussianBand2D(table, spline_kwargs={'k': 1, 's': 0})

Bases: object

Gaussian band model.

This 2-dimensional model is Gaussian in y for a given x, and the Gaussian parameters can vary in x.

One application of this model is the diffuse emission along the Galactic plane, i.e. x = GLON and y = GLAT.

Parameters:

table : Table

Table of Gaussian parameters. x, amplitude, mean, stddev.

spline_kwargs : dict

Keyword arguments passed to UnivariateSpline
