discov_num notes refcode
WSI 121 Both 2MASS J05100427-2340407 and J05100488-2340148 are binaries in the
AstraLux images, so since they are separated by only 27" on the sky
and have very similar proper motions (e.g. Roser et al. 2010), this is XXX2010
likely a quadruple system in reality. Common proper motion remains to
be confirmed for both of the close components. Jnn2012
