论文摘要
在这项工作中，我们更详细地评论了Cardoso等人首先提出的参数化框架发生了什么。当与Schwarzschild背景度量偏离时，以及“动力学”的可能偏差。我们在背景度量标准中处理可能的偏差，并具有有关原始作品的其他系数。当应用于参数估计问题时，此重新制定的优点很明显，因为系数始终是真实的，并且其中许多不取决于频率的泛音数和角动量，因此最终减少了要推断的参数总量。
In this work we comment in more detail on what happens to the parametrized framework first presented by Cardoso et al. when there are departures from the Schwarzschild background metric, as well as possible deviations in the "dynamics". We treat possible deviations in the background metric with additional coefficients with respect to the original works. The advantages of this reformulation are clear when applied to a parameter estimation problem, since the coefficients are always real, and many of them do not depend on the overtone number and angular momentum of the frequency, thus eventually reducing the total amount of parameters to be inferred.
