# These variables correspond to the Valencia formulation

# HydroBase uses the following conventions:
#    M = M_sun
#    c = G = 1

# We also assume the following constants of nature:
#    c    = 299792458.0 m/s
#    G    = 6.67428e-11 m^3/kg/s^2
#    mu0  = 4 pi 1.0e-7 N/A^2
#    eps0 = 1 / (mu0 c^2)
#    M_sun = 1.98892e+30 kg

# This corresponds to the following units:
#    [M] = M_sun
#    [L] = [M] (G / c^2)
#    [T] = [L] / c
#    [B] = 1 / [L] / sqrt(eps0 G / c^2))
