discov_num notes refcode
CHR 37 A Delta Scuti-type variable and long-period (1300d) SB.
Hipparcos astrometric solution adopted some elements from the orbit of HIP1997d
Griffin (1984). Grf1984a
A spectroscopic orbit with a period of 1300 days was determined by
Christie (1936 ApJ, 83, 433). The many negative results listed here
may be due to a large or variable magnitude difference.
