Notes. ADI observations of the target list in Table 1. The IRDIS side of the observations was obtained in dual-band mode (H2-H3 and K1–K2 for IRDIFS and IRDIFS-EXT, respectively), except for CQ Tau, for which the full Ks band was used. References for the inclination (Inc) and position angle (PA) of the disks can be found in Appendix A.
