Left: same as Fig. 7 with peculiar outliers indicated on the diagram. Additional constrains of J–K_S > 1.6 mag, K_S < 7.80 mag (M_bol <−8.0 mag), K_S < 8.70 mag (M_bol < −7.1 mag) and K_S > 5.77 mag(<30M_⊙) are shown by the dashed-dotted lines. Targets inside this region are likely to be either super-AGBs or RSGs. Right: same as Fig. 13 with peculiar outliers indicated. Considering luminosity, color and MIR variaility from both panels, it appears that the No. 13 and 22 might be super-AGBs while No. 679 might be a dust-obscured RSG.
