Luminosity-age diagram for all RSGs in NGC 330, stars that have RV measurements from the present study are marked with a cross. Luminosities are derived the J-band magnitude calibration of Davies et al. (2013). Using the least luminous RSGs, we estimate the age of the NGC 330 to be 45 ± 5 Myr. SMC-like evolutionary tracks from Brott et al. (2011) are used to estimate ages, and Bressan et al. (2012) tracks are shown to highlight differences between models.
