Observed fX/fg ratios for X-ray sources with Gaia counterparts and parallax (blue data points) and with Gaia counterparts but no parallax (red data points). For comparison we also plot the fX/fg ratios derived by Schneider et al. (2022) for the coronal sources in the eROSITA EFEDS-field (small black data points); see text for more details.
