AI总结：
HEIMDALL工具通过分析散射测距容忍参数与最小搜索深度的关系，改进快速射电暴样本的调查完整性分析。
摘要：
快速射电暴（FRB）是可检测到宇宙学距离的短暂发射闪光。宇宙学应用依赖于对检测样本与底层人口关系的理解。为此，我们检查了FRB搜索工具HEIMDALL使用的散射测距容忍参数，并提供了该参数与最小搜索深度之间的关系。几个FRB样本可以使用此方法更准确地考虑调查完整性。
英文摘要：
Fast radio bursts (FRBs) are brief flashes of emission detectable to cosmological distances. Cosmology applications rely on an understanding of how the detected sample relates to the underlying population. To this end we examine the dispersion measure `tolerance' parameter employed by the FRB search tool \textsc{heimdall} and provide the relation between this and minimum search depth. Several FRB samples can be `retro-fitted' using this to more properly account for survey completeness.
