Table 2 lists the average estimated abundances for the FCLS, GKLS, SSA, and SSA-H methods in the five test regions. The “truth” (actual physically measured) percent by volume of DiDy for these regions varied slightly from the goal of 100%, 75%, 50% 25%, and 0%. In reality, these were measured as 100%, 78.8%, 50.5%, 24.2%, and 0% for DiDy100, DiD075, DiDy050, DiDy025, and DiDy000, respectively. Results for the GKLS method using a fixed gamma of , , , , , , , and are given, as well as for the automated GKLS. This table shows FCLS to be poor at predicting the abundances for DiDy075 (93.11% predicted versus 78.8% truth) and DiDy050 (74.97% predicted versus 50.5% truth), as well as very poor at predicting DiDy025 (63.88% predicted versus 24.2% truth). The results of GKLS for small values of agree with theoretical expectations of an approximately linear model. Specifically, the prediction of GKLS at is almost exactly the same as the FCLS method.
