Notes. Neutrino fluxes on Earth, Φ, are in units of cm⁻² s⁻¹. The numbers highlighted in bold indicate the values that satisfy the constraints or have χ² <  1. The K2-MZvar-A2-12 model is our best model with a variable accretion metallicity. Two constraints of (Z/X)_surf are shown for the models with the AGSS09 (top) and GS98 (bottom) compositions. See Sect. A.2 for the description of models. This table is available in electronic form at the CDS and Zenodo. ^a V+17 refers to Vinyoles et al. (2017, see their Tables 4 and 6). We derived the χ² of their models assuming a perfect matching of the luminosity and effective temperature. ^bF+20 refers to Farag et al. (2020, see their Tables 1, 2, and 3). We note that rms(δc_s), Φ(pep), and Φ(¹⁷F) are not available; thus, Φ(CNO) = Φ(¹³N) + Φ(¹⁵O) for their models. ^cOur simulations with the same settings as Farag et al. (2020). References.
