Image depths (5σ in a 3 arcsec circular aperture), computed from the noise in each tile for the narrow bands (left) and broad bands (right). The colored symbols indicate the survey average values in each filter, while the gray symbols indicate the values in each of the four miniJPAS pointings. For the narrow bands, the dashed gray line indicates the approximate target minimum depth of J-PAS from Benítez et al. (2014).
