Left: comparison between the contrast for β Pic obtained with TRAP on: (1) aligned data not taking into account the brightness modulation; (2) same but taking into account the brightness modulation; and (3) unaligned data with the brightness modulation. TRAP was run with 30% of available principal components. The shaded areas around the lines correspond to the 14–84% percentile interval of contrast values at a given separation. Right: contrast gain compared to aligned data without including amplitude variations (baseline reduction). Figure description is analogous to that of Fig. 7.
