Fig. 9


The I(86.84 Å)/I(87.02 Å) line intensity ratio plotted as a function of logarithmic electron density (Ne in cm-3) at logarithmic electron temperatures (Te in K) of log Te = 5.7, 5.9 and 6.1. The experimental ratio of 1.2 from the Chandra spectrum of Procyon (Raassen et al. 2002) is plotted as a dashed line, while the ratio corrected for the presence of an Fe xi blend in the 87.02 Å feature (1.5) is shown as a dashed-dot line.
