Notes. The first three lines give the systematics on parallax in microarcseconds for various G-magnitude ranges (in mag). The last line provides the systematic uncertainty on the distance modulus (in mag). We note that σseismo is not available for the faintest magnitude range because it has been estimated using Kepler stars, which do not become faint enough. As σspectro has been found not to vary with G, its value remains constant. The total systematic uncertainty was computed by adding the individual uncertainties in quadrature.
