Averaged mass (upper panel) and 1σ mass uncertainty (lower panel) vs. spectral type for PHZmid and for four masses: 1 MEarth (red), 2 MEarth (green), 3 MEarth (brown), and 4 MEarth (orange). The thickness corresponds to the range covered by the spot contrast. The solid horizontal line indicates the 10% objective for PLATO, and the dashed line shows an indicative level of 20%.
