High-contrast residual images after PSF removal with the LOCI algorithm for both filters NB_1.75 and NB_2.12. Each panel is a  sub-image centered on the target star. The bottom set of panels is a zoom-in of the inner 1″ × 1″ region for the NB_2.12 filter showing the PSF residuals at small distances from the primary. No speckles were found to be achromatic (i.e., no evidence for a real object) and present in the two epochs of HD 135344B (~1.5 month apart) and TW Hya (just a few days apart) for which only the best dataset is displayed. North is up and east to the left.
