Reduced HD 32297 ADI images. a) LOCI reduction b) PCA reduction, both in logarithmic stretch and units of mJy/arcsec2. c) and d) correspond to a) and b) S/N images, respectively, in a [-5σ, 5σ] linear scale. All the images have been convolved with an aperture of diameter ~FWHM. The black arrows in the S/N maps point out the locations of the potential gaps at distances of ~0.75″ (NE side) and ~0.65″ (SW side) from the blocked star, marked with a white cross. The diameter of the black mask is ~0.4″.
