Disentangled spectra obtained from the 12 mock binaries, spanning three K₁,K₂ (left to right, input values given in uppermost row) sets and four secondary light contributions (top to bottom, input values given in leftmost column). The bottom row (l₂ = 0) corresponds to BH companions. The K₁,K₂ values derived from grid disentangling are shown in the header of each panel, with values in parentheses denoting results from poorly constrained solutions. The disentangled spectra are scaled by their respective light ratios, except for the bottom row, where the scaling assumes l₂ = 3% (factor 33 amplification).
