a) Distance distribution of the CoRoT stars. b) Relative uncertainty on the distance estimation as a function of the distance (bottom). The dotted line represents the 50% threshold. c) Comparison of our distance estimate with parallaxes for the S4N sample (Allende Prieto et al. 2004). Note that the uncertainty on the distance determination from parallaxes is about 1% (hence not always represented).
