Caption: Figure 9.

Same as Figure 7, but for NGC 5634. As with NGC 5897 (Figure 8), at the depth of DELVE DR2 our model suggests that the underlying tidal tail of this GC is marginally detectable in the presence of no Milky Way foreground (middle panel). At the full LSST depth, the same model suggests that the stream ought to be detectable in the presence of no foreground and potentially even with the addition of Milky Way foreground (bottom right panel); although, likely only with updated search parameters (e.g., a larger smoothing kernel, wider field of view).
