Comparison of SPB stellar parameters from the NN with literature values. From top to bottom, the difference between the values in this paper and the ones from literature catalogues are shown for T_eff, log g, v sin i, and [M/H]. Both the errors obtained from the NN and those from the literature are propagated to get the shown error bars. The different symbols correspond to Lehmann et al. (2011; grey crosses), Balona et al. (2011b; pink stars), Pápics et al. (2015;red pluses), Frasca et al. (2016; green triangles), Pápics et al. (2017; purple squares), Zhang et al. (2018; orange reversed triangles), and Hanes et al. (2019; blue circles).
