First method for calculating a true distance modulus, μ_o and E(B − V). Data points correspond to the distance modulus from each band plotted as a function of inverse wavelength, λ⁻¹. A reddening-law fit to the moduli (excluding 4.5 μm) is plotted as the solid line. The Cardelli et al. (1989) reddening law was used with a fixed R_v = 3.1 and E(B − V) and μ_o allowed to vary. The resulting fit provides an extinction-corrected distance modulus of 23.38 ± 0.05 mag and E(B − V) = 0.36 ± 0.09.
