Derived [X/Fe] abundance ratios for the RSGs in the Perseus complex from the NIR (top panel, red symbols) and optical (central panel, blue symbols). Bottom panel: the average [X/Fe] for each element for NIR (red symbols) and optical (blue symbols) with the average error bars. Values are solar-scaled according to the Grevesse & Sauval (1998) solar reference, except for oxygen, for which we used Asplund et al. (2009).
