Table 1

Characteristic model-measurement variances for 10 lines. The number of flares considered for each line is given in Column H. The F-Test critical values for the F (N_flr, N_flr) distribution at the 1% significance level are given in Column I. The characteristic variance is the N_flr/e smallest variance of the flares analyzed and reported for the 3 model variants, L(XXIII), L(XVIII) and L((XXIII)) discussed in the text. For reference, variances are given in Column D which correspond with differences found using normalized Fe XXIII light curves. Comparing Columns E–G with Column D shows better model-measurement agreement for all three model variants. However, there is a marked increase in model-measurement disagreement for the the model variants for lines cooler than Fe XV. Column J gives the correlations between measured τ values and those predicted by a method discussed in Section 5.
