Caption: Figure 4.

The [α/Fe] abundances for APOGEE-2S LMC and SMC RGB stars (black) and AGB-O stars (red), with S/N ≥ 80 and the ASPCAP STARBAD flag not set. Representative statistical uncertainties are shown at the bottom for both RGB and AGB samples. The chemical distribution of AGB-O stars matches that of the RGB stars quite well, though the former include few stars below [Fe/H] = −1.4.
