  "abstract": "The physics goals of NOvA are the constraints of neutrino oscillation parameters such as the octant of $\\theta_{23}$, $\\delta_{\\rm{CP}}$, and the neutrino mass hierarchy via a joint fit to $\\nu_{\\mu}$ and $\\nu_{e}$ oscillation spectrum. We do this by propagating $\\nu_{\\mu}$ from the world's most intense neutrino beam at Fermilab, over a baseline of 810 km to northern Minnesota, USA, and measure the $\\nu_{\\mu}$ to $\\nu_{e}$ oscillation probability. NOvA announced its latest oscillation results, based on 8.85$\\times10^{20}$ (6.9$\\times10^{20}$) protons on target neutrino (antineutrino) data. Preliminary results for the allowed values of oscillation parameters are: $\\Delta m^2_{32}=2.51^{+0.12}_{-0.08}\\times 10^{-3} \\mathrm{eV}^2$, $\\mathrm{sin}^2\\theta_{23} = 0.58 \\pm 0.03$ (upper octant), and $\\delta_{\\rm{CP}}=0.17\\pi$ with preference to the normal hierarchy. Reliable constraints on these oscillation parameters require a rigorous treatment of systematic uncertainties and thorough cross-checks. In this paper, we present an overview of the treatment of systematic uncertainties as well as cross-checks using muon removed simulations and cosmic muon bremsstrahlung showers.",
