Abstract

An erratum is presented to correct the errors in two equations in Sect. 3 of [Opt. Express 14, 9508-9521 (2006)].

The last two unnumbered equations of Sect. 3 of Ref. [1] are written with wrong indices, and in the second equation a minus sign is missing. The correct equations read

〈 Γ_{μ; \overset{̅}{η} η}^{(ext)} 〉 = c_{Γ} \sum_{plm} s_{μ; lm} \sum_{\overset{̅}{p} \overset{̅}{l}} W_{lηl, m - μ}^{(p)} {\overset{̅}{𝒮}}_{lm \overset{̅}{l} m}^{(p \overset{̅}{p}) *} W_{I \overset{̅}{η} \overset{̅}{l} m}^{(\overset{̅}{p}) *},

An identical error affects the analogous equations on p. 105 of Ref. [2]. Nevertheless, we stress that the calculations reported both in Refs. [1] and [2] were performed using the correct formulas.
