Equivalent widths measured for the 12CO (2, 0) line and Brγ line for YSOs (blue stars) and late-type stars (black dots). We separate the two populations approximately using the dashed line at EW(Brγ) = 10 Å. Different symbols and colours represent the classification of the SIMBAD matches to our sources by searching within 2.̋0 (see Sect. 3.1).
