(a) ln[I*(q)] versus q2 Guinier plots of the averaged and concentration/standard-normalized top peak frames for all the six Gaussian peaks derived from the decomposition of the hpHMW-FG SE-HPLC-SAXS data shown in Fig. 5. The data included in the linear regressions (straight lines) are indicated with filled symbols. All linear regressions were done with SD weighting with automatic rejection of outliers (set at ±2 SD) after definition of an appropriate q2 range, limited by the qmaxRg < 1.3 rule. (b) The Guinier plots for G-pks #4 (blue), #5 (magenta) and #6 (black) are shown on an expanded scale. (c), (d) Cross-section ln[qI*(q)] versus q2 Guinier plots for the same data as (a) and (b) (for the reason of clarity, G-pk #5 has been omitted, only one-half of the actual points are shown for all data sets, and the regression lines were prolonged at unphysical q2 < 0 values while the q2 = 0 axis is shown as a vertical gray line). Two linear regions were fitted, both limited by the qmaxRc < 1 rule, for G-pks #1 and #2 [(c), lower q2 range, dashed lines; higher q2-range, solid lines], and one for all others [solid lines; G-pk #3, (c); G-pks #4 and #6, (d)].
