RBR 20 Triple system. The Riddle et al. (2015) companion at 2".2 is confirmed RAO2015
as physical by its fixed position and its location on the CMD. The .
main star is a double-lined spectroscopic binary with P = 6 yr (D. .
Latham 2012, private communication) and estimated semimajor axis of .
0".1. Our standard algorithm, fitstars, produced subpar results on .
this star and instead we used the deconvolution technique used in .
Riddle et al. (2015) to analyze this star. It is resolved here at .
0".07. The magnitude difference of Aa,Ab (dK = 2.43) matches the .
spectroscopic mass ratio of 0.52 and corresponds to the Ab mass of .
0.60 Msun. The orbital motion of Aa,Ab can be followed with AO and .
speckle interferometry. R br2015d
