GaussianShell([radius, width, bkg_scale])

2-D Gaussian shell (ring) signal with isotropic normal background.

class nami_toys.shell.GaussianShell(radius=2.5, width=0.25, bkg_scale=1.5)

Bases: object

2-D Gaussian shell (ring) signal with isotropic normal background.

Parameters:

• radius (float) – Mean radius of the signal ring.

• width (float) – Standard deviation of the radial spread.

• bkg_scale (float) – Standard deviation of the isotropic background Gaussian.

bkg_scale: float = 1.5
