Notes. Photometry in the optical, near-infrared, and mid-infrared from SDSS DR9 (York et al. 2000; Ahn et al. 2012), 2MASS Point Source catalogue (Cutri et al. 2003; Skrutskie et al. 2006), UKIDSS Galactic Plane Survey and Galactic Clusters Survey (Lawrence et al. 2007; Lucas et al. 2008), and AllWISE (Wright et al. 2010), as well as the mean proper motion determined in this paper. There is no reliable detection in the SDSS i filter and the WISE w3 band.
