Spectral energy distributions of four white dwarfs analyzed as part of this work, selected to highlight the difference between H- and He-dominated atmospheres in the J-PLUS passbands. The colored points in all the panels are the 3 arcsec diameter photometry corrected to total magnitudes from J-PLUS (squares for broad bands, ugriz; circles for medium bands, J0378, J0395, J0410, J0430, J0515, J0660, and J0861). The gray diamonds connected with a solid line show the best-fitting solution, with the derived parameters and their uncertainties labeled in the panels: effective temperature (T_eff), surface gravity (log g), parallax (ϖ), and probability of having a H-dominated atmosphere (p_H). The unique J-PLUS identification, composed by the TILE_ID of the reference r−band image and the NUMBER assigned by SExtractor to the source, is also reported in the panels for reference. Sources with T_eff ∼ 16 000 K (top panels) and T_eff ∼ 10 000 K (bottom panels) are presented. Left panels: sources with H-dominated atmospheres, p_H = 1. Right panels: sources with He-dominated atmospheres, p_He = 0.
