Carmona et al. (2007) reanalyzed the data obtained by Perez et al.
Crm2007
(2004), resulting in a change in his position angle from 353 to 4deg.
Pez2004
Muller et al. (2011) resolved the B component into a close pair, which
MuA2011
they referred to as BC. However, the C component is a long-known
distant member of the system, so the close pair has been renamed
Glp1892f
MUA 1 Ba,Bb. They derive the following parameters for the close
members of the system:
component: A Ba Bb
spec: F0IIIe K7V M1V
L (Lsun) 12.7 +6.4/-3.7 0.50 +0.24/-0.20 0.41 +0.19/-0.16
