Optical and NIR E(V − X)_host (where X = u, B, g, r, i, Y, J, H) color excess measurements of SN 2016adj, plotted as a function of the effective wavelength of passband X. Each color excess measurement represents the difference between the observed color (corrected for E(B − V)_MW) and the intrinsic color-curve template for SN Ic shown in Fig. 9. The red dashed line corresponds to the best Fitzpatrick (1999) reddening law model fit characterized by a ratio of total-to-selective absorption $R_V^{\text{host}}$ = 5.7 ± 0.7 and a visual extinction $A_V^{\text{host}}$ = 6.3 ± 0.2 mag. Also shown are the best Fitzpatrick (1999) reddening law model fits with $R_V^{\text{host}}$ = 3.1 (blue dashed line), and the best-fit Goobar (2008) power-law model (green dashed line).
