Line analysis of data from Henderson et al. (1998) giving corrected saturations and relative permeability points from the intercepts, and slope values C_s, C_c, C_g to be used for derivation of capillary pressure for each fraction F. Condensate was less wetting than gas for all fractions, hence C_g was not reported for any fractions.
