Erratum: "Is there a metallicity-luminosity relationship in active galactic nuclei? The case of narrow-line Seyfert 1 galaxies"

Description: This erratum corrects a computational error affecting the calculation of the intrinsic luminosities of several objects in the article "Is there a metallicity-luminosity relationship in active galactic nuclei? The case of narrow-line Seyfert 1 galaxies." This does not affect any of the main results of the article.
