>From looking at the source code: The program uses per amino acid values for the extinction coefficient. It gets them from the Eamino.dat data file in the EMBOSS distribution. Extinction coefficients are based on the values of Gill and von Hippel (1989) Anal Biochem 182 319-326.
It sums the values over the sequence and reports that. It then calculates the 1mg/ml value by taking the above value and dividing it by the molecular weight.
