K_S – IRAC color excesses for the candidate members of NGC 2244 with SpT or T_eff measurement. Orange circles represent KMOS bona fide members, blue squares KMOS possible members and gray diamonds represent VIMOS objects and Mužić et al. (2022) members. Big black circles represent the objects that we found to have infrared excess. The locus of sources from the literature with full disks is represented with orange contours, and the locus of sources without disks is represented with blue contours (see Appendix B). Black dashed line represents the 0.25 mag excess boundary.
