Comments 
P.1827 right column 3rd paragraph: "The most obvious method assumes that the partitioned areas aDPPC(x) and achol(x) are constants independent of x. Then, the plot of a(x) versus x should be a straight line. In this way, Chiu et al. (primary source) obtained the results aDPPC = 0.507 nm^2 and achol = 0.223 nm^2 for large values of x. However, Fig. 1 suggests that a linear fit is inadequate for small values of x." For large values of x. See BNID 105804 Tablehttp://bionumbers.hms.harvard.edu/files/Areas%20a%20(x)%20per%20total%20lipid%20and%20cholesterol%20versus%20molecular%20fraction%20cholesterol%20x%20from%20three%20sets%20of%20simulations.pdf for range in various values of x.
