Stellar (red dots) and galaxy (blue squares) number counts as a function of r-band magnitude in four J-PLUS EDR pointings (labelled in the panels). Coloured solid histograms are the stellar (yellow) and galaxy (green) number counts from SDSS in the same area. Black solid histograms are the stellar number counts at the pointing position estimated with the default TRILEGAL model of the Milky Way (Girardi et al. 2005). White symbols are galaxy number counts from the literature: Yasuda et al. (2001; circles); Huang et al. (2001; triangles); Kümmel & Wagner (2001; inverted triangles); and Kashikawa et al. (2004; diamonds). The dashed vertical line marks the value of μ_p estimated for each pointing, showing the expected magnitude with the same number density of stars and galaxies.
