Not-quite-transcendental Functions for Logarithmic Interpolation of Tabulated Data

Blog Article

From tabulated nuclear and degenerate equations of state to photon and neutrino opacities and nuclear reaction rates, here tabulated data is ubiquitous in computational astrophysics.The dynamic range that must be covered by these tables typically spans many orders of magnitude.Here we present a novel strategy for accurately and performantly interpolating tabulated data that spans these large dynamic ranges.We demonstrate the efficacy of this strategy in tabulated lookups for nuclear and terrestrial equations of state.

We show that canine spectra kc 3 intranasal single dose this strategy is a faster drop-in replacement for linear interpolation of logarithmic grids.
