Additional set of ejecta models.

Model	Description
M17-m-s-z-smc	Same as M17-m-s but with SMC metallicity
M17-m-s-z-lmc	Same as M17-m-s but with LMC metallicity
M17-m-s-Ni-l	Same as M17-m-s but with a ⁵⁶Ni mass of 0.1 M_⊙
M17-m-s-Ni-h	Same as M17-m-s but with a ⁵⁶Ni mass of 0.15 M_⊙
M17-m-vs	Same as M17-m-s but with a contrast factor of 210 in the core

Notes. All are based on the M17-m-s model and have an initial mass of 17 M_⊙, medium mixing, strong expansion, M_H = 0.027 and X_H = 0.54 if not otherwise stated.
