Fig. 3
Proper motion analysis of CC 1 and 2 detected around HAT-P-57. PA and separation are evaluated individually. The dashed cone presents the expected position of a gravitationally bound companion considering potential orbital motion of the object. The grey trajectory represents the expected location of a stationary background object, instead. For the MMT/Clio2data we adopted the separation measurement presented Hartman et al. (2015); no PA of the source at this epoch is provided.
