Notes. Compiled from all-sky surveys (2MASS: Skrutskie et al. 2006; CMC15: Muiños & Evans 2014; AllWISE: Cutri & et al. 2013; Gaia: Gaia Collaboration 2018), CC14: Cortés-Contreras et al. 2014, or measured by us on digitizations of photographic plates (Digital Sky Survey digitizations of the Quick-V Northern survey used for the Hubble Space Telescope Guide Star Catalogue 1, and SuperCOSMOS digitizations of blue, red, and infrared Palomar Observatory Sky Survey). We also investigated the latest data releases of the Astrographic Catalogue, AKARI, Gaia DR1, and PanSTARRS, among others.
