Apparent magnitudes in the Gaia G (blue) and VISIONS H (red) passbands as a function of mass for objects at a distance of 400 pc. Solid lines represent a case of young stars with an age of 10 Myr located in a region with A_K = 0.1 mag foreground extinction. The dashed lines represent field stars at an age of 1 Gyr without any foreground extinction. The dotted vertical and horizontal lines mark the hydrogen burning limit (HBL) and the surveys' sensitivity limits, respectively.
