Hubble residuals versus the now-corrected ΣHα within 1 kpc surrounding each SN Ia. Squares represent Iaα SNe Ia, while circles represent those categorized as Iaϵ. Among the Iaϵ, those with lighter gray belong to M1, while those with darker gray are in M2. The two SNe Ia that are overly bright and that have now moved above the SFR threshold (vertical dashed line) are shaded light blue. The original means of the M1 and M2 subsamples are shown as horizontal lines, and labeled accordingly. It can be seen that the two modes have moved slightly closer together. The upper panel shows the ΣHα histograms for the corrected (solid line) and the original (dashed line) values.
