discov_num notes refcode
CHR 226 Ba,Bb: This close companion to RST4888 has been observed on three
occasions, but has shown little movement over a 1.6-year period. The
1989 measurements of the Rossiter pair were originally published by
McAlister et al. (1990) and Hartkopf et al. (1993). Following McA1990
discovery of the close pair in the 1990 data, these 1989 data were Hrt1993
rereduced, resulting in "preconfirmation" of the new component. Hrt1996b
V438 Pup, Algol-type eclipsing binary, P = 4.9350 d. Zas2011
The new pair was initially given component designations Aa,Ab, but
it was uncertain which component of the Rossiter had been split.
Tokovinin et al. (2015) have determined it was the B component, so the Tok2015c
pair has been changed to Ba,Bb.
