摘要
事件视界望远镜（EHT）对黑洞偏振分辨图像的解释，需要针对特定黑洞吸积系统模型，预测地基仪器可观测的偏振发射。此类预测由广义相对论辐射转移（GRRT）代码生成，其在弯曲时空积分偏振辐射转移方程。本文评估了 EHT 合作组内使用的一组光线追踪 GRRT 代码在生成若干测试图像时的准确性与一致性，表明各种辐射转移计算的方法与实现具有高度一致性。在对解析吸积模型成像时，我们发现所有代码生成的图像在最坏情况下像素级归一化均方误差（NMSE）为 0.012 以内相似。在对基于网格的磁流体动力学模拟快照成像时，我们发现所有测试图像在 Stokes I、Q、U 和 V 上的 NMSE 分别不大于 0.02、0.04、0.04 和 0.12 时相似。我们还发现与已发表 EHT 结果相关的若干图像度量值的一致精度远优于测量不确定度。
