标题： Not-Quite-Transcendental Functions For Logarithmic Interpolation of Tabulated Data

摘要： 从表格化的核物质和简并状态方程到光子和中微子的不透明度，再到核反应速率：表格数据在计算天体物理学中无处不在。 这些表格必须覆盖的动态范围通常跨越多个数量级。 在这里，我们提出了一种新颖的策略，用于准确且高效地插值这些大动态范围的表格数据。 我们展示了该策略在核物质和地球状态方程的表格查找中的有效性。 我们表明，这种策略是线性插值对数网格的更快的\textit{插入式}替代方法。 显示英文摘要

摘要： From tabulated nuclear and degenerate equations of state to photon and neutrino opacities, to nuclear reaction rates: 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 this strategy is a faster \textit{drop-in} replacement for linear interpolation of logarithmic grids.
