Erratum to Determination of the Integrated Luminosity at HERA using Elastic QED Compton Events

A measurement of the integrated luminosity at the ep collider HERA is presented, exploiting the elastic QED Compton process ep → eγp. The electron and the photon are detected in the backward calorimeter of the H1 experiment. The integrated luminosity of the data recorded in 2003 to 2007 is determined with a precision of 2.3%. The measurement is found to be compatible with the corresponding result obtained using the Bethe-Heitler process. Accepted by Eur. Phys. J. C F.D. Aaron, C. Alexa, V. Andreev, S. Backovic, A.
