discov_num notes refcode
CHR 57 39 Her. A short-period (2.3d) double-lined spectroscopic binary.
Hence a triple.
This system, first announced by McAlister and recalled in a later McA1984b
McAlister paper after repeated attempts at confirmation, has been McA1993
restored. While perhaps still spurious, the subsequent confirmation or
suspected duplicity (by another technique) makes the discovery
measurement somewhat more probable.
