CHR 128 4 Lyn.
WAL 45 AE: No good match to Wallenquist's estimated 0deg, 70" astrometry for Wal1947
this pair. Since he gives dm values for AB,C, AB,D, and AB,E, it is
apparently not the AD pair at ~0deg, 100". Best guess is that there is
a typographical error and he meant 30deg, 70", in reasonable agreement
in astrometry and photometry with a pair at 31deg, 77".
