Notes. Parameters that were not varied were set based on previously reported values in literature (Pueyo 2016; Greenbaum et al. 2018; Cantalloube et al. 2015). For ANDROMEDA, the first column of parameters was used for the SPHERE data, and the second column for the GPI data. The oversampling parameter S is defined in Eq. (1). Further information about each of these parameters is available in the documentation of each package.
