1 Erratum to: Eur. Phys. J. C (2015) 75:406 https://doi.org/10.1140/epjc/s10052-015-3624-1

Due to an oversight of ours in proofreading and a communication problem with the publisher, the figures published in F. Becattini et al. Eur. Phys. J. C (2015) 75:406 were not correct. This Erratum contains the correct figures (Figs. 2, 3, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15) as in arXiv:1501.04468 [v2], submitted on March 12 2015, and the post-publication version arXiv:1501.04468 [v3], submitted on August 17 2015.
