μδ vs. μα⋆ plot for the known YSO candidates and for the co-moving sources. Filled red circles represent proper motion values of known YSO candidates in L1147/1158, L1172/1174, and L1177. Open black squares mark PV Cep, HD 200775, and BD+68°1118. The open blue circles represent the same for the co-moving sources. The gray ellipse shows the boundary of the proper motion values considered when selecting the co-moving sources. The open black circles represent sources not satisfying the six times the MAD conditions in distance and proper motion values. The dashed lines show the median values of μα⋆ and μδ.
