discov_num notes refcode
TOK 400 HIP 60574 is a spectroscopic triple with periods 14d and 22yr (Latham
2012, private communication), also an acceleration binary. We resolved
the outer pair at 0".22 separation, matching the spectroscopic period.
The lines of the visual secondary Ab could potentially be detected in
the spectrum by cross-correlation, leading eventually to a full 3-D
orbit. Tok2015c
