Example of input image. Left: high resolution PSF (α = 18°) for a target with P = 12.3 (barycentre designated by the black dot) surrounded by several contaminants (respective barycentres designated by the magenta dots). The brightest contaminant in the frame (tagged below the target) has P = 13.7. All other contaminants are at least 2 mag fainter than the target. Right: corresponding low resolution PSF (imagette) at pixel level. Zodiacal light is not shown in the scene. Dashed white lines represent pixel borders.
