Proper motion analysis of TYC 8252-533-1 B. The colored markers represent the relative offsets in RA and Dec with respect to the primary that we measured in SPHERE and NACO imaging data or derived from the Gaia DR2 and EDR3 catalogs. The blue dashed line illustrates the trajectory of a static background object at infinity and the white markers along the curve represent the hypothetical positions of such an object at the epoch of the corresponding observation.
