WDS 20538+3723 SEI 1299 AB : NOTES
 
 
discov_num notes refcode
SEI1299 AB: ALI 675.
SEI1301 AC: No star seen on Aladin at AC2000 coordinates of primary. Published
measure corresponds to difference between nonexistent primary and real
B component. Thus the AC measure appears to be another AB measure but
with an error in the coordinates of the A component.
