Notes. The third column shows the number of LISA-detectable DWDs in the MW model that overlap with the sky location of each GC, as described in Sect. 2.5. The fourth through seventh columns show the numbers if we impose an additional constraint that we only consider MW DWDs whose error ellipses are smaller than a size threshold. The final column shows the expected number of MW DWDs within the 10° grid around each GC, based on the sky location probability distribution of those DWDs.
