      abstract     = {We generalize and update our former top quark mass
                      calibration framework for Monte Carlo (MC) event generators
                      based on the $e^+e^-$ hadron-level 2-jettiness $\tau_2$
                      distribution in the resonance region for boosted $t\bar t$
                      production, that was used to relate the PYTHIA 8.205 top
                      mass parameter $m_t^{\rm MC}$ to the MSR mass $m_t^{\rm
                      MSR}(R)$ and the pole mass $m_t^{\rm pole}$. The current
                      most precise direct top mass measurements specifically
                      determine $m_t^{\rm MC}$. The updated framework includes the
                      addition of the shape variables sum of jet masses $\tau_s$
                      and modified jet mass $\tau_m$, and the treatment of two
                      more gap subtraction schemes to remove the ${\cal
                      O}(\Lambda_{\rm QCD})$ renormalon related to large-angle
                      soft radiation. These generalizations entail implementing a
                      more versatile shape-function fit procedure and accounting
                      for a certain type of $(m_t/Q)^2$ power corrections to
                      achieve gap-scheme and observable independent results. The
                      theoretical description employs boosted heavy-quark
                      effective theory (bHQET) at next-to-next-to-logarithmic
                      order (N$^2$LL), matched to soft-collinear effective theory
                      (SCET) at N$^2$LL and full QCD at next-to-leading order
                      (NLO), and includes the dominant top width effects.
                      Furthermore, the software framework has been modernized to
                      use standard file and event record formats. We update the
                      top mass calibration results by applying the new framework
                      to PYTHIA 8.205, HERWIG 7.2 and SHERPA 2.2.11. Even though
                      the hadron-level resonance positions produced by the three
                      generators differ significantly for the same top mass
                      parameter $m_t^{\rm MC}$ value, the calibration shows that
                      these differences arise from the hadronization modeling.
                      Indeed, we find that $m_t^{\rm MC}$ agrees with $m_t^{\rm
                      MSR}(1\,\mbox{GeV})$ within $200$ MeV for the three
                      generators and differs from the pole mass by $350$ to $600$
