Summary of the disk biases with standard and disk-specific ADI reduction strategies. Flux losses and FWHM changes were measured on data with and without speckle noise respectively, for an initial disk parametrized with i = 75°, αin = 5 and αout = −2.5. The rADI and LOCI parameters are Nδ = 1.5, NA = 300, g = 1, except for conservative LOCI, which has Nδ = 2, NA = 1000 and g = 0.5.
