    3 Acknowledging suggestions by Gavin P. Salam (CERN) and J. Thaler (MIT)
     3The first incarnation of the Valencia algorithm (with two parameters R and beta) was proposed "A robust jet reconstruction algorithm for high-energy lepton colliders", PLB 750 (2015) 95-99, arXiv:1404.4294
     4The authors acknowledge suggestions by Gavin P. Salam (CERN) and his help in assessing the IR safety of the algorithm
    45
    5 A preprint motivating the algorithm and describing its performance is available on: "A new jet algorithm for lepton colliders", arXiv:1404.4294 (submitted to PLB)
     6The VLC algorithm (with three parameters R, beta and gamma) is described in "Jet reconstruction at high-energy electron-positron colliders", EPJC 78 (2018) no. 2, 144. The addition of the gamma parameter was suggested by J. Thaler (MIT). The performance of the algorithm is evaluated in detail in this paper, in collaboration with Ph. Roloff, R. Simoniello (CERN) and M. Boronat, J. Fuster (IFIC)

     8        Incorporates a modification suggested by
     9        Filip Zarnecki (Warsaw) to make sure the behaviour for negative
     10        beta is correct (added to trunk in june 2017 but left out of
     11        2.0.1)

     19        Bug fix: a bug was discovered in the plugin by Matthias Weber (CERN)
     20        the calculation of the distance diB assumed massless constituents.
     21        The impact on the results - jet energy and mass - is typically small,
     22        but can be non-negligible
