事件视界望远镜（EHT）发布了对M87星系中心超大质量黑洞附近视界尺度毫米辐射重建图像的分析。部分分析利用了一个大型的合成黑洞图像和光谱库，这些图像和光谱是使用数值广义相对论磁流体力学流体模拟和偏振射线追踪产生的。在这篇文章中，我们描述了PATOKA管道，这是用来产生伊利诺伊州的EHT模拟库的贡献。我们开始描述相关的吸积系统和辐射过程。然后，我们描述了我们使用的三个数字代码iharm、ipole和igrmonty的详细信息，并特别注意当前一代代码与最初发布版本之间的差异。最后，我们提供了一个简短的概述，模拟数据产生的PATOKA和结论的局限性和未来的方向进行了讨论。
The Event Horizon Telescope (EHT) has released analyses of reconstructed images of horizon-scale millimeter emission near the supermassive black hole at the center of the M87 galaxy. Parts of the analyses made use of a large library of synthetic black hole images and spectra, which were produced using numerical general relativistic magnetohydrodynamics fluid simulations and polarized ray tracing. In this article, we describe the PATOKA pipeline, which was used to generate the Illinois contribution to the EHT simulation library. We begin by describing the relevant accretion systems and radiative processes. We then describe the details of the three numerical codes we use, iharm, ipole, and igrmonty, paying particular attention to differences between the current generation of the codes and the originally published versions. Finally, we provide a brief overview of simulated data as produced by PATOKA and conclude with a discussion of limitations and future directions.
