勘误：冷球形星际介质中引力波的色散
Erratum: Dispersion of gravitational waves in cold spherical interstellar medium
摘要：
发表在IJMPD 27（4）：1850040，2018上的这项研究提供了由于星际介质中色散引起的GW频移的数值结果。为了调整第2.1节中原本不匹配的“背景”时空的度规函数，作者采用了达穆瓦-以色列结条件。在第4.1节中，由于缺少转换因子，原始论文中使用的代码错误地计算了瞬态事件GW 150914的频移幅度。在这两种情况下，数字错误和潜在的矛盾已经确定和消除，进行调整，以保持与密切相关的早期研究的一致性。
英文摘要：
The study published in IJMPD 27(4):1850040, 2018 provided a numerical result for the frequency-shift of GWs due to dispersion in interstellar medium. In order to adjust the metric functions of the originally improperly matched `background' spacetime in sections 2.1, the authors have adopted Darmois--Israel junction conditions. In section 4.1 the code used in the original paper erroneously computed the magnitude of frequency-shift for the transient event GW150914 due to a missing conversion factor. In both cases where numerical errors and potential contradictions have been identified and eliminated, adjustments were undertaken in order to maintain consistency with closely-related earlier studies.
