Comparison of R_V estimated in the vicinity of SNe with estimates from direct observations of SNe. Blue dots are estimates obtained using late-time (several years post maximum light) multiwaveband photopolarimetry in the vicinity of SNe. Black squares are estimates based on model fitting to color LC data of those SNe (Mandel et al. 2011; Phillips et al. 2013; Burns et al. 2014; Amanullah et al. 2015; Gutiérrez et al. 2016). The median, and its uncertainty, of each estimation are presented by dashed lines in the corresponding color. The fiducial R_V for the Milky Way is presented by a red line with its uncertainty being the shaded orange area. A 2.5σ separation is observed between the median of R_V estimates obtained with photopolarimetry and with LC data.
