log_pressure_reparameterization_conversion

log_pressure_reparameterization_conversion(scaled_pressure_ratio, scaled_pressure_2)

Converts the reparameterization joining pressures from (scaled_pressure_ratio, scaled_pressure_2) to (log10_pressure_1, log10_pressure_2).

This reparameterization with a triangular prior (with mode = max) on scaled_pressure_2 and a uniform prior on scaled_pressure_ratio mimics identical uniform priors on log10_pressure_1 and log10_pressure_2 where samples with log10_pressure_2 > log10_pressure_1 are rejected. This reparameterization allows for a faster initialization. A minimum log10_pressure of 33 (in cgs units) is chosen to be slightly higher than the low-density crust EOS that is stitched to the dynamic polytrope EOS model in LALSimulation.

Parameters:

scaled_pressure_ratio, scaled_pressure_2: float

reparameterizations of the dividing pressures

Returns:

log10_pressure_1, log10_pressure_2: float

joining pressures in the original parameterization
