Table 2: Abundance ratios with respect to Fe for various phases (A-E) of the large flare (values rounded to multiples of 0.1), and for the low-level pre-flare section (Q). All values are normalized with the solar ratios. The basic solar abundances of Anders & Grevesse (1989) have been used, except for Fe for which the value given in Grevesse & Sauval (1999) has been adopted. Errors are based on 1$\sigma $ errors of the individual abundances (see text for details). "Fe/Fe'' is unity by definition, but the error bars indicate the fractional uncertainty of the Fe abundance. The last line gives the Fe abundance relative to solar photospheric values.
