Data file needed for implementation of the Helmholtz equation of state in the Phantom smoothed particle hydrodynamics and magnetohydrodynamics code

** this file is downloaded automatically on running Phantom **This is a datafile containing information needed to utilise the Helmholtz equation of state (Timmes & Swesty 2000) implemented in the Phantom smoothed particle hydrodynamics and magnetohydrodynamics code (Price et al. 2018). Primarily used to model degenerate matter in white dwarfs For information about how to read the file and its contents, refer to the relevant module in the phantom source code (eos_helmholtz.f90)
