Distribution of the metallicity offsets for J-PLUS DR2. In all the panels, the initial offsets Δ𝒳_FeH from ISL magnitudes are presented in gray, and the final offsets computed with ISL+ZSL magnitudes are in color. From top to bottom and left to right, passbands J0378, J0395, J0410, J430, J0515, J0660, J0861, and z are shown. The colored solid line shows the Gaussian distribution that better describe , with its dispersion labeled in each panel. The black solid line depicts the convolution of a pulse function of width s_ISL with a Gaussian function of dispersion .
