Notes. Coronal abundances are taken in quiescent- (Q) or low-activity state, where available. The original assumed solar photospheric values are indicated in the last column, which were all converted to Asplund et al. (2009) and Ne from Drake & Testa (2005). If there were available stellar photospheric abundance (ph. a.) measurements for a star, the source is also given in the last column. The FIP bias and its uncertainty are calculated as the mean and standard deviation of [X/Fe]cor−[X/Fe]phot, where X can be C, N, O, and Ne. The FIP bias column is corrected by +0.084 according to Wood et al. (2018), except for the stars listing (1) as source. As discussed in Sect. 2, GJ 338 AB is omitted.
