• Faithfull backport of Tracking hgh beta star 2018 #23238, commit-wise and code-wise
• (From the comments written while signing the original PR now merged in the master):
  • Track reconstruction parameters to be used for the 2018 CMS-TOTEM run at large beta*
    They are defined in a dedicated era, and therefore do not affect normal reco sequences and workflows
  • Comparison with the current tracking show a larger acceptance of low pt particles, which is instrumental for the run on low-pileup events and the reconstruction of soft tracks
  • Overall CPU increase is kind of 5-10% of the total reco time, which is still deemed acceptable for the special runs where this config is required
