In [ 1], which appeared in the November/December 2009 issue of IEEE TVCG (volume 15, number 6, pp. 1291-1298), there were typos in (17) and (18). The correct version of these equations are below:

\eqalignno{&L_{a}(\lambda) = \alpha \, L(\lambda) + \left(1 - \alpha\right) \, 0.96 \, {{Area_{L}}\over{Area_{M}}} \, M(\lambda),&(17)\cr&M_{a}(\lambda) = \alpha \, M(\lambda) + \left(1 - \alpha\right) \, {{1}\over{0.96}} \, {{Area_{M}}\over{Area_{L}}} \, L(\lambda).&(18)}

Note that all images and results shown in the paper and provided in the supplemental materials were produced using the correct equations.
