Left: footprint of the miniJPAS survey, with its four individual pointings shown as red squares (see their coordinates in Table 4). miniJPAS overlaps with the footprints of other projects, also shown for reference: EGS (in green), pointing #6 of the ALHAMBRA Survey (in violet), the W07 wide field of the HSC-SSP (large circle in pale blue), field W3 of the CFHTLS (in yellow), OSIRIS Tunable Emission Line Object survey (OTELO, http://research.iac.es/proyecto/otelo/pages/otelo.php; small square close to the center of the figure), and SDSS (in light gray occupying the whole area). We refer to Table 9 for the references to these overlapping surveys. Right: g, r, i color image of miniJPAS, with zoom in three selected areas.
