I 226 Wagner et al. (2016) imaged a Jovian exoplanet orbiting the primary at
a distance of ~80au. They also resolved the Innes B component into a
70mas pair, which they designate as B and C. However, the C component
designation is already in use for Innes' 30" companion. Also, their B
designation redefines B from the photocenter of the previously
unresolved close stellar pair to one component of that pair. We have
therefore designated the two stars as Ba and Bb, in keeping with our
usual hierarchical designation scheme.
Wagner et al. derive the following parameters for system components:
