The dataset, collected with the ATLAS detector in proton--proton collisions at $\\sqrt{s}=13$ TeV delivered by the Large Hadron Collider, corresponds to an integrated luminosity of 140 fb$^{-1}$. The analysis targets events in the lepton-plus-jets decay channel, with an electron or muon from a semi-leptonically decaying top quark and a hadronically decaying top quark that is sufficiently energetic to be reconstructed as a single large-radius jet. The mean of the invariant mass of the reconstructed large-radius jet provides the sensitivity to the top quark mass and is simultaneously fitted with two additional observables to reduce the impact of the systematic uncertainties. The top quark mass is measured to be $m_t = 172.95 \\pm 0.53$ GeV, which is the most precise ATLAS measurement from a single channel.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.158358.v1/t1","@type":"Dataset","description":"Values and uncertainties for the parameters of interest in the profile likelihood fit to $\\overline{m_J}$, $m_{jj}$, and $m_{tj}$ using data....","name":"Post-fit values and uncertainties for parameters of interest"},{"@id":"https://doi.org/10.17182/hepdata.158358.v1/t2","@type":"Dataset","description":"Post-fit central values and uncertaintes for the nuisance parameters (including MC stat uncertainty terms) used in the profile likelihood fit...","name":"Post-fit values and uncertaintes for nuisance parameters"},{"@id":"https://doi.org/10.17182/hepdata.158358.v1/t3","@type":"Dataset","description":"Covariance matrix for the profile likelihood fit to $\\overline{m_J}$, $m_{jj}$, and $m_{tj}$ using data.","name":"Covariance matrix from profile likelihood fit"},{"@id":"https://doi.org/10.17182/hepdata.158358.v1/t4","@type":"Dataset","description":"Pre-fit MC statistical uncertainties per bin.
