Comparison between the different zero point estimations for J-PLUS DR1 and those presented in this work. The y-axis present the difference ΔZP_m  =  Δ𝒳_atm + Δ𝒳_WD + 25 − ZP_m, where the index m covers the different calibration methods: spectro-photometric standard stars (SSS), broad-band SDSS photometry (SDSS), synthetic photometry from SDSS spectra (spec), and stellar locus regression (SLR). Aperture corrections were applied to the SDSS, spec, and SLR methods (see text for details). The grey areas show differences of 0.01, 0.05, and 0.1 magnitudes in the zero points, and the dotted lines indicate identity. The points and their error bars represent the median and the dispersion of the difference distributions.
