Median residuals between the observed and synthetic magnitudes as a function of the mean wavelengths of the passbands for mini-JPAS (blue), J-PLUS in APOGEE DR16 (red), and J-PLUS WDs (green). In grey lines, we plot the Gaia passband transmissivity as in Gaia EDR3 (Riello et al. 2021) divided by a factor three to fit in the same scale of the residuals. The solid grey line represents G band, the short dashed line BP band (at shorter wavelengths), and the long dashed line RP band (at longer wavelengths).
