Fig. 4: Sensitivity of the data fits the scale length of CH and Be.

a1, b1 Shows the density profiles when we change the scalelengths on the CH and the Be side correspondingly. The curves in (a2, b2) are intensity lineouts from data (black dashed lines), best fit (red solid lines), shorter scale lengths (blue solid lines), and longer scale lengths (green solid lines). The variation is ± 20% in LCH and LBe.
