Notes. H95 and K21 are the identification of these sources from Hunter et al. (1995) and Khorrami et al. (2021), respectively. K2018, K2015, H, and J are the magnitudes in the SPHERE/IRDIS filters (Khorrami et al. 2017, 2021). I, V, and U are the magnitudes in the HST F814W, F555W, and F336W filters (Hunter et al. 1995). μx and μy are the 2D PMs estimated from their position shift within 3.06 years in the left and right data.
