本文研究事件视界望远镜合作组织在处理黑洞观测数据以生成单一图像时面临的多种渲染方式选择，通过审视各阶段认知与美学选择，探讨不同选择下图像呈现，指出最有价值证据来自特定选择的有限可变性。
AI 中文摘要
2019年，事件视界望远镜合作组织（EHT）发布了首张基于观测的黑洞阴影图像。本文指出，尽管EHT强调以单一图像作为最终结果，但在渲染数据时有无数种合理方式，研究人员难以抉择。从极噪且稀疏的数据中获取单一图像，需在数据处理各阶段选择多种合理方法之一或对不同方法结果求平均。我们审视了各阶段涉及的认知与美学选择，探讨若EHT做出不同选择图像会怎样。我们认为EHT产生的最有价值证据并非来自其最终宣传的核心单一图像，而是特定选择所呈现的有限可变性。
英文摘要
In 2019, the first image of a black hole's shadow based on observation was released by the Event Horizon Telescope Collaboration (EHT). This paper shows that despite the EHT's emphasis on a single image as its final result, there were countless plausible ways of rendering the data, among which researchers could not easily choose. To obtain a single image from the extremely noisy and sparse data, it was necessary to select one of multiple plausible approaches, or to average the results from different approaches, at each stage of data processing. We examine the epistemic and aesthetic choices involved at various stages, and explore what the images would have looked like if the EHT had made different choices. We suggest that the most valuable evidence produced by the EHT comes not from the single image it ultimately advertised as its central result, but from the demonstration of the limited variability that emerged from the specific choices made.
