Caption: Figure 8.

Synthetic two-component spectra created by combining HD 145742 with various spot coverages represented by the spectrum of GJ 4099. The flux-weighting of the spots conspires to make it extremely difficult to measure small spot coverage, though larger spot coverages can be measured robustly.
