Notes. Abundances are with respect to Anders & Grevesse (1989). Abundances provided for each FIP group for the 2005 Aug. 15th RGS data are numerical averages of the elements fitted by Güdel et al. (2007b). The discrepancy between the NH derived from the 2005 Aug. 15th CCD (3.4 × 1021 cm−2) and RGS data (4.9 × 1021 cm−2) was already noted by Güdel et al. (2007b).
