Gaia colour-magnitude diagram for objects in our catalogue labelled by confidence classes compared to the distribution of LMC stars (colour mesh) selected by proper motions and with overlaid contours for different stellar types (proper motion selection and stellar evolutionary phases from Gaia Collaboration (2021) evolutionary phases in Sect. 2.3.1 and figure 2; Young 1: very young main sequence (age < 50 Myr), Young 2: young main sequence (50 Myr < age < 400 Myr), BL: blue loop, RGB: red giant branch, AGB: asymptotic giant branch). The colour scale of the colour mesh gives the number of sources in each colour-magnitude bin. The bin sizes are 0.01 mag and 0.02 mag for BP−RP and G, respectively. Note that the majority of objects from confidence classes 1−5 lie in or close to the area of very young main-sequence stars, which is to be expected for Be stars. Several objects of confidence class 6 deviate strongly from this, which might indicate misidentifications.
