X-ray-to-optical flux ratio (log  (FX/FV)) distribution of the stellar population of this survey compared to that of: field, Hyades and Pleiades stars representing old, intermediate and young populations respectively. We show the log  (FX/FV) distribution for spectral ranges A–M (left panel), F–G (middle panel), and K–M (right panel). In dark grey we show the location of giant star candidates. For comparison purposes, the total number of field, Hyades and Pleiades stars has been normalised to match the same number as our stellar content.
