Notes. Column Area is the region area in square degrees. Column Mtot is the total number of M stars. Column Net reports the net number of M stars. Column Density is the net M-star density in units of stars/sq.deg.. Column fC gives the number ratio between M non-members and all M stars in the given subregion. Columns Hα, NIR, UV, and OB report numbers of Hα emission, NIR-excess, UV-excess, and (net) OB stars, respectively.
