Ratio of the total extinctions between our reconstructed extinction map and that of Green et al. (2019) as a function of the extinction threshold used. For each extinction threshold, we calculate the total amount of extinction above that value for each map and plot the ratio between the two (the Y axis). This is a proxy of the total mass of the cloud within that threshold. The blue line is a curve fit to the points using an X-Spline with shape = 0.5 (Blanc & Schlick 1998). The dashed line indicates the total extinction ratio of 0.5.
