Fig. C.3.
Spectral type sequence for supergiants from the SMC at λ/δλ ~ 3 700 in the range from 4200 to 4450 Å. The stars are shown from top to bottom: (upper panel) 61296 (G5 Iab) [2011 field-1-smc 356], 30135 (G8 Ia–Iab) [2012 field-1-smc 115], and 49033 (K1 Iab) [2012 field-1-smc 325]; (lower panel) 50840 (K3 Iab) [2012 field-1-smc 340], 11939 (K5 Iab) [2012 field-1-smc 138], and 18592 (M1 Iab) [2012 field-1-smc 186] (taking into account that H is in emission in this star). The wavelength is given in angstrom..
