Estimating cluster extinctions for Pleiades (a,e), Praesepe (b,f), Hyades (c,g) and NGC884 (d,h). The top row shows likelihood maps of cluster extinction μ and global uncertainty estimate σ. Contours show 68%, 90%, 95% and 99% confidence regions. The horizontal dashed line indicates our global uncertainty estimate of 0.46 mag from Sect. 6.5. Vertical dashed lines are A_G ~ (0.6−1.0) × A₀ (Jordi et al. 2010, Fig. 17 therein) for literature estimates of A₀ ~ 3.1 × E(B − V) from Pandey et al. (2003). The bottom row shows, for each cluster, the histogram of estimated A_G (black) and the maximum-likelihood estimate of the truncated Gaussian (red).
