小行星9729831 这份建议书写得不好。摘要和介绍中所述的目标表明循环推理和测试是无法完成的。然而,在第6页,有一个明确的声明,他们将测试的假设,轴向深度/或MBS可以作为地壳厚度的代理。 我们一直关注的是利用重力数据作为地壳厚度的代用指标,这项工作将检验这一代用指标。由于地壳厚度仍有可能随时间发生变化,这将不是一次确定性的测试,但它将是对这一问题的系统研究。我们同意专家组的意见,并建议给予一年的奖励。
英文摘要
9729831 Cochran The proposal is not well written. The goals as stated in the abstract and introduction suggest circular reasoning and tests that cannot be done. On page 6, however, there is a clear statement that they will be testing the assumption that axial depth &/or MBS can be used as a proxy for crustal thickness. We have been concerned with the use of gravity data as a proxy for crustal thickness, and this work will test that proxy. It will not be a definitive test since there is still the possibility of temporal changes in crustal thickness, but it will be a systematic study of the problem. We agree with the panel and recommend a one-year award.
