Gaia Data Release 2 sky map in colour.The map is a map of the measured brightness, or flux, of the almost 1.7 billion sources in Gaia DR2. It is a combination of three other maps, separately compiling the fluxes measured in the Gaia G, G BP and G RP photometric bands. These individual maps are built by adding, or integrating, the flux of all sources that fall within each pixel The first RVS measurements are published in the Gaia Data Release 2 (DR2,Sartoretti et al.2018), providing an unprece-dented 6D map of the Milky Way (Gaia Collaboration2018b). The RVS is an integral-field spectrograph with resolving powe In this work, we take advantage of the groundbreaking Gaia data release 2 to select ELM candidates with well-defined selection criteria, covering the whole sky and the full-range of temperatures predicted by the models, taking the first step towards an all-sky, complete, and unbiased ELM sample
