The upper panel shows the SEP/photospheric and 1.2xslow solar wind (SSW)/photospheric abundance ratios as a function of FIP. Curves help show the trends of each data set. The lower panel shows the ratio of the “coronal” abundances from SEPs to those of the slow SW (Bochsler 2008), as a function of FIP. The dashed line suggests the preferred normalization factor of 1.2. Adopted from Reames (2018)
