discov_num notes refcode
B 2527 FIN measures 1951-1959 distance less than 0.1".
AB pair bound; change in separation and angle consistent with orbital
motion. B component likely M2-M5 dwarf with mass 0.24 +/- 0.01 Msun.
C and D components likely unrelated. Egn2007
AB: Likely a spurious pair. Last measured 1961 and unresolved by SOAR
on 3 occasions 2010–2013. Tok201
AB: Tentative resolution by Finsen, 1 speckle measure at 0.040" in
2001.08, unresolved by Hipparcos, 3 non-resolutions by SOAR 2010-2013.
AB can be "ghost". Tok2014d
EGN 27 AE: E companion was not detected by RoboAO in 2013.05, below limit. Tok2014d
