Red supergiant region of the Hertzsprung–Russell diagram for all identified RSG candidates in each program galaxy compared with the evolutionary tracks from Brott et al. (2011) for the SMC metallicity and the evolutionary tracks from Georgy et al. (2013) for Z = 0.002. For each target we present the results obtained from different techniques: the SED technique (, L^SED), I-band technique (, L^(I−band)), J − K technique (, L^{(J − K)}), and the V − K technique (, L^{(V − K)}).
