This graphic on the left shows the angular distribution of measured neutron yield versus the direction in spherical polar coordinates as a color plot. The red spot represents a region of the compressed fuel that is thinner and has more neutron yield detected. The graphic on the right shows parts of the simple model that approximates 192 beam spots and 2-3 diagnostic windows at the hohlraum wall that produce a net mode-1 in drive at the capsule that is correlated with the hotspot velocity vector direction and magnitude.
