(a) Total, Q, and SF-SMFs from this study shown as orange circles, red squares, and blue triangles, respectively, with bootstrapping errors. Schechter fits are shown as dashed orange, dash-dotted red, and dotted blue lines. (b) Total SMF from J-PLUS DR3 (orange circles), compared to Peng et al. (2010) (gray pluses), Xu et al. (2025) (cyan hexagons), Baldry et al. (2012) (purple points), and Díaz-García et al. (2024) (dashed orange curve). GAMA SMFs from Wright et al. (2018) are shown as green, brown, and purple triangles with different orientations. (c) SF-SMF from J-PLUS DR3 (blue triangles), with the blue-shaded region showing total uncertainty (statistical plus systematic). This is compared to Baldry et al. (2012) (dash-dotted black curve), Peng et al. (2010) (cyan pluses), Xu et al. (2025) (light-blue hexagons), and Díaz-García et al. (2024) (dashed light-blue curve). (d) Q-SMF from J-PLUS DR3 (red squares), with the total uncertainty shown as a red-shaded region. This is compared to Baldry et al. (2012) (dash-dotted black curve), Peng et al. (2010) (dark red pluses), Xu et al. (2025) (light-red hexagons), and Díaz-García et al. (2024) (dashed dark-red curve).
