Offsets and dispersions of the residuals between our data and the literature. Dispersions are 1 scatter of the residuals. Beuing et al. (2002) do not compute G4300 and Ca4227 indices. For G4300 and Ca4227 indices González (1993) and Longhetti et al. (1998) used a (slightly) different definition than Trager et al. (1998) and consequently comparisons are not reported in the table. The comparison for H index between our data and those of Trager et al. (1998) and Beuing et al. (2002) are made using uncorrected data.
