discov_num notes refcode
HDS3244 A 0.9 arcsecond binary was published in 1985 and given the designation McA1987a
CHR 115. This pair was subsequently deemed spurious after numerous
failed confirmations. Reinspection of the 1985 data, post Hipparcos, McA1993
yielded a weak measure in good agreement with the Hipparcos
observation and subsequent speckle observations (see Mason et al. Msn1999b
1999). This binary was incorrectly still listed as CHR 115 in Mason Msn1997c
et al. (1997), however.
Primary is V360 Lac, Beta Lyr-type eclipsing binary, period 10.075d. Zas2013
