Notes. (a) Gaia BP/RP low-resolution spectra and the plane correction to account for 2D variations along the CCD were used to homogenize the photometry. Precision was estimated from duplicated main sequence stars in overlapping pointings (Sect. 4.1). (b) Uncertainty in the absolute color calibration from the Bayesian analysis of the white dwarf locus (Sect. 3.3). (c) Final precision in the J-PLUS DR3 flux calibration, 
, where σr = 5 mmag (Sect. 3.4). (d) Accuracy estimated from the comparison of the final calibration with results from the stellar color regression method (Sect. 4.2).
