Elemental abundances of (top) DoAr 21, (middle) ROXs 21, and (bottom) ROXs 31. Errors indicate 90% confidence limits. The horizontal axis shows corresponding elements with their FIP values (eV). Gray squares, open circles, and filled circles represent abundances in the quiescent, first, and second flare phases, respectively.
