Residuals between the synthetic photometry from Gaia BP/RP spectra and J-PLUS photometry in the J0378, J0395, J0410, J0430, 𝑔, J0660, and i passbands (from top to bottom). The panels, from left to right, show the residuals as a function of the G magnitude and the G_BP − G_RP color without the transformation terms and and as a function of the G magnitude and the G_BP − G_RP color after applying them. The color scale depicts the number density of sources using a logarithm scale, with nearly 1.5 million sources shown. In all the panels, the solid red line represents the median of the residuals, and the dashed lines show its one σ dispersion.
