论文摘要
热白矮人（WD）模型大气的非本地热力学平衡（NLTE）计算是Hubble空间望远镜（HST）和CalSpec数据库的现代通量校准的基石。这些理论光谱能量分布（SED）提供了相对通量与波长，只有绝对通量水平仍有待使VEGA在MID-IR中Sirius的中途空间实验（MSX）值的测量的Vega的绝对通量进行调解。由\ textsc {tlusty}和\ textsc {tmap} NLTE模型大气的最新SED代码用于主要WDS G191-B2B，GD153和GD71的SED代码，与以前的1 \ 2000年相比，从1500〜Å至30〜 \ sybormon hommon Homenthiments g191-B2B，GD153和GD71的代码提高了1 \％从1500〜的1 \％。这些新型热WDS的新型NLTE模型现在提供了从FUV到MID-IR的一致通量标准。
Non-local Thermodynamic Equilibrium (NLTE) calculations of hot white dwarf (WD) model atmospheres are the cornerstone of modern flux calibrations for the Hubble Space Telescope (HST) and for the CALSPEC database. These theoretical spectral energy distributions (SEDs) provide the relative flux vs. wavelength, and only the absolute flux level remains to be set by reconciling the measured absolute flux of Vega in the visible with the Midcourse Space Experiment (MSX) values for Sirius in the mid-IR. The most recent SEDs calculated by the \textsc{tlusty} and \textsc{tmap} NLTE model atmosphere codes for the primary WDs G191-B2B, GD153, and GD71 show improved agreement to 1\% from 1500~Å to 30~\micron, in comparison to the previous 1\% consistency only from 2000~Å to 5~\micron. These new NLTE models of hot WDs now provide consistent flux standards from the FUV to the mid-IR.
