CMDs showing α (red lines) and β (blue lines) selection criteria on full LMC data. To the right (redward) of the red line is the α section of the CMD, where we expect to find massive YSOs and little contamination from non-YSO sources. The blue lines mark the boundary of the β-selection, in which we expect more contamination, particularly from background galaxies. List YSO candidates plotted are the full lists of W08 and GC09.
