The formula for the flux density per unit length (Eq. (8) in the paper of Fischera & Martin 2012) contained the product δην. Since the notation ην already incorporates δ implicitly, the correct form is (8)

This is a notational error, not used in our calculations, and so it does not affect any of the results.
