Trial Dispersion Measure Spacing in Fast Radio Burst Searches with HEIMDALL
Abstract
Abstract 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 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.
