SALT2 stretch x₁ vs. color c. Left: the local perspective. SNe markers and x₁ and c marginalized stacked distributions follow the same color-shape code as Fig. 6. Right: the global perspective. Open-blue squares show the globally star-forming hosts and red dots show the globally passive hosts (log (sSFR) ≶ −10.5 respectively). Big markers indicate SNe with local measurements, while small markers denote SNe not in our local sample (failed redshift cut, but passed the quality cuts, see Sect. 2.1). Stacked histograms are the marginalized distributions of x₁ and c using the marker color codes. These figures compare to Fig. 2 of Lampeitl et al. (2010). Notice the mix of local environments for moderate x₁ while low x₁ are almost exclusively from passive environments.
