Erratum: ``Discovery of an Extraordinarily Massive Cluster of Red Supergiants'' (ApJ, 643, 1166 [2006])

Equations (1) and (2) were set incorrectly in the published version of this paper; the equivalence appearing in the denominator should in fact be the final value on the right-hand side. The correct forms of these equations are:A_Ks=(E_H-K)/((λ_H/λ_Ks)^-1.53-1)=1.55-0.21/((1.662/2.159)^-1.53-1)=2.73,

(1)andA_Ks=(E_J-K)/((λ_J/λ_Ks)^-1.53-1)=4.62-0.89/((1.2352./2.159)^-1.53-1)=2.76. (2)
