H 4 113 H IV 113. B is BD+38@4320. Also known as STF2748.
SMY 6 AD: Based on his magnitude estimates, the 1875 Ward measure attributed Wrd1876
to EH was more likely AD.
WRD 4 AG: Ward's 1875 EG measure doesn't correspond to any likely companion,
but given his magnitudes, the measure was probably between A and a
companion now labelled as G. The old EG pair has been removed. The
WRD 4ED should more appropriately have been designated SMY 6ED, but
will not be changed, in order to minimize confusion.
