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 |
