Left: p̂_R vs. the PG estimate of E(B − V) for stars farther than 250 pc (circles). Values of [p_R/E(B − V)]_max equal to 9% and 13% are indicated with black the solid and dashed lines, respectively. The linear fit to the data has a slope of 15.9 ± 0.4% mag⁻¹ (orange line and 1σ uncertainty shown by shaded region). Each star is colored according to its distance (colorbar). Right: effect of uncertainty in E(B − V). A linear fit to the data from each reddening map (PG, orange, SFD, red, PDL, cyan, G18, green) is shown (shaded regions as in left panel). The weighted mean p̂_R and E(B − V) is shown for the E(B − V) from PG (orange circle), SFD (red diamond), PDL (cyan square), and G18 (green triangle).
