Photo-spectra of the four miniJPAS sources with BP/RP spectra released in Gaia DR3. Colored symbols are the same as in Fig. 2. The solid black and brown lines in the left panels show the reconstructed spectra from the basis coefficients without and with truncation, respectively. The white dots in the right panels present the synthetic photometry computed from the BP/RP full reconstructed spectra and the J-PAS photometric system. No offset has been applied to the Gaia DR3 flux scale.
