Lick Hδ_A absorption index versus Hα emission EW for our final 52 TDE host sample. The background shows the SDSS comparison sample with contours at σ-equivalent probability levels (6.7–93.3%). The solid and dashed boxes mark the E+A and QBS regions, respectively. To avoid label overlap, our gold and silver hosts near the origin are not individually labeled since many are clustered there.
