Comparisons of the best model fits with different assumptions. (a) Strict Porod decay without angle correction. (b) Strict Porod decay with angle correction. (c) SAS decay without angle correction. (d) SAS decay with angle correction. Experimental scattering data recorded at the lowest foam height (h = 7 cm, black squares) are shown together with the (angle-corrected) reflectivity (dotted blue lines), the Porod/SAS contribution (dashed green lines) and the total model fitting curve (solid red lines). The quality of the fit is judged by the value of χ2.
