Comparing peak SN magnitude (including color correction) with SALT2.4 x1 (left panel) and uTi (right panel). Lighter shaded points were found in R17 to originate in locally passive regions, and likely from old progenitors, while dark blue points were found in regions dominated by star formation. These are separated in x1 (left), but not in uTi (right).
