WDS 10454+3831 CHR 191 AB : NOTES
 
 
discov_num notes refcode
CHR 191 1983.4277: The AB pair is a new component to the 0".7 pair HO 532.
HO 532 This new component was actually first resolved in 1983 (McAlister et
al (1987), but it was believed at the time that the measurement was of McA1987b
the known pair (the wide component laid outside the processor "window"
of our old autocorrelator). Reprocessing of our archival video data
allowed us to resolve both components in the 1983 and 1984 data sets,
although both early measurements of the AB pair are quite weak.
