CAMDs combining several Gaia, 2MASS, and WISE magnitudes. The top row represents all sources with available measurements, and the bottom row shows the subset with quality flags A or Β in the corresponding 2MASS and AllWISE catalogues. A kernel density estimate is shown using a grey scale. The transparency and the symbol sizes were chosen to enhance the visibility of the main densities. The colour code reflects the estimated T_eff as indicated by the colour bar at the lower-right edge of the figure.
