Microphysics inputs are crucial for simulations of stellar collapse and core-collapse supernovae. Two key microphysics components are the equation of state (EOS) and neutrino opacities.

We provide here the EOS driver routines and EOS tables used in simulations of the the Caltech computational relativistic astrophysics group. We also provide the routines we use to create the tables from the original data tables provided by the various nuclear theorists.

We provide here some discussion on the current state of our neutrino opacities, available via GitHub
