NLTT 50746/50747 Chm2004
JNN 290 BC and BD: G 212-27. Both of the point sources in the AstraLux field
of view are consistent with static background objects that do not
share a common proper motion with the primary star, hence they are
contaminants rather than physical companions. Their colors (dz' = 4.0
+/- 0.3 mag and di' = 3.3 +/- 0.5 mag for the closer point source and
dz' = 4.8 +/- 0.3 mag and di' = 4.3 +/- 0.1 mag for the farther one)
verify this conclusion. Jnn2014
