WDS 18224+4545 A 700 : NOTES
 
 
discov_num notes refcode
A 700 Round 1951-1954. Possible quadrant change.
Increasing residuals since the orbital solution by Heintz (1998) led Hei1998
to the determination by Parent et al. (2017) that the relative motion
of the pair was better represented by a rectilinear fit. Thus the pair
appears to be an optical double rather than a physical binary. CC_2017b
Rectilinear solution by Parent et al. (2017). CC_2017b
