Abstract

An erratum is presented to correct the errors in two equations in Sect. 2 of [Opt. Express 15, 11984-11998 (2007)].

© 2007 Optical Society of America

In Eqs. (10) and (11) of Ref. [1

] two factors are missing. Moreover, in Eq. (11) r̂′ should be changed into Y 1μ(r̂′). The correct equations read

Iζlml′m′(pp′)=Ω′(r′̂v̂ζ)ipp′Zlm(p)*(r′̂)Zl′m′(p)(r′̂)dΩ′=4π3μY1μ*(v̂ζ)il′l16π2Kμ;lml′m′,(pp′)
(10)

and

Kμ;lml′m′,(pp′)=16π2ill′Ω′Y1μ(r′̂)ipp′Zlm(p)*(r′̂)Zl′m′(p)(r′̂)dΩ′.
(11)

The factor 16π 2 i l-l must be inserted in Eq. (11) to ensure that the integrals K (pp′) μ;lmlm are just those reported in Refs. [2
