Notes.
Instrumental stellar locus (ISL), the plane correction to account for 2D variations along the CCD, and the metallicity-dependent stellar locus (ZSL) were used to homogenize the photometry. The calibration was anchored to PS1 photometry for gri passbands. Precision estimated from duplicated MS stars in overlapping pointings.
Uncertainty in the color calibration from the Bayesian analysis of the white dwarf locus (Sect. 4.3).
Final precision in the J-PLUS DR2 flux calibration, 
, where σr = 5 mmag (Sect. 4.3).
Accuracy along the surveyed area estimated from the difference between the median Δ𝒳FeH of the 30 pointings with lower and larger absolute latitude when the ISL magnitudes were used (Sect. 4.2).
Accuracy along the surveyed area estimated from the dispersion in Δ𝒳FeH when the ISL+ZSL were used to homogenize the photometry.
Accuracy estimated from the comparison of the final ISL+ZSL calibration with results from the stellar color regression method (Sect. 4.5).
