Notes. The dates (and the start times below) of the FCS observations that were selected and averaged for this analysis are shown. The second column indicates the NOAA number. The third column indicates the nature of the count rates in the SMM BCS Ca xix channel. The fourth column indicates whether the neon abundance was found to be high, standard (Std.), or low by Schmelz et al. (1996). The last column shows our measured FIP enhancement of iron with respect to neon and oxygen, relative to the Asplund et al. (2009) photospheric abundances, and assuming that neon and oxygen do not vary.
