It can be difficult to develop an effective and balanced search strategy in SETI, especially from a funding perspective, given the diverse methodologies and myriad orthogonal proposals for the best technosignatures. Here I propose a framework to compare the relative advantages and disadvantages of various proposed technosignatures based on nine ‘axes of merit’. This framework was first developed at the NASA Technosignatures Workshop in Houston in 2018 and published in that report. I give the definition and rationale behind the nine axes as well as the history of each axis in the SETI and technosignature literature. These axes are then applied to three classes of technosignature searches as an illustration of their use. An open-source software tool is available to allow technosignature researchers to make their own version of the figure.

技术签名搜索的九个优点

考虑到最佳技术签名的多样化方法和无数正交提案，在 SETI 中制定有效且平衡的搜索策略可能很困难，特别是从资金的角度来看。在这里，我提出了一个框架来比较基于九个“优点”的各种提议的技术签名的相对优缺点。该框架于 2018 年在休斯顿的 NASA 技术签名研讨会上首次开发，并在该报告中发表。我给出了九个轴背后的定义和基本原理，以及 SETI 和技术签名文献中每个轴的历史。然后将这些轴应用于三类技术签名搜索，以说明它们的使用。可以使用开源软件工具来允许技术签名研究人员制作他们自己的图形版本。
