Gas-to-dust ratio of the MCS in units of the Milky Way’s median value of $\frac{N_{\mathrm{H}}}{E(\mathrm{B}-\mathrm{V})}=(0.63\pm 0.05)\times {10}^{22}\frac{{\mathrm{cm}}^{-2}}{\mathrm{mag}}$. Contour lines mark the values that are between two and five times higher, for comparision with Welty et al. (2012) and Koornneef (1982). The circles mark the H I absorption lines detected by Kobulnicky & Dickey (1999, black), while the white one marks the MALS pointing position reported here.
