Combined normality test analysis for the sph2 ADI sequence. (a) PCA-pmap showing the combined p-value both as a colour code and as values, as a function of the distance to the star through the rolling annulus (x axis) and the number of principal components used in the PCA-based PSF subtraction (y axis). Yellow star markers indicate when the null hypothesis H₀ (Gaussian noise) is rejected. The white dashed line shows the 90% CEVR at each rolling annulus. White circles in bold highlight the principal component that maximizes the S/N of fake companion recoveries. (b) Percentage of yellow star markers, or H₀ rejection, (y axis) for each rolling annulus (x axis) on the PCA-pmap. The dashed black line highlights the selection criteria for setting the dominant noise at each rolling annulus. (c) Final representation of estimated noise regimes along the processed frames field of view. Grey areas in each subplot highlight the inner working angle (denoted as IWA).
