Caption: Figure 4.

The predicted gamma-ray light curves at energies above 3.5 MeV given very neutron-rich ejecta from an NSM located at 10 kpc. Line color notations are the same as Figure 3. The result given the prompt photon spectrum of ²⁵⁴Cf fission found when photon emission is calculated using FREYA instead of GEF (red dotted line) is also shown.
