Sky distribution in galactic coordinates of previously known and RR Lyrae stars that are new discoveries by Gaia and that are confirmed by the SOS Cep&RRL pipeline. Orange points: known RR Lyrae stars that do not have a counterpart among the SOS-confirmed RR Lyrae stars published in DR2. Green points: known RR Lyrae stars that are cross-matched with SOS-confirmed RR Lyrae stars. Black points: new RR Lyrae detected by Gaia and confirmed by the SOS Cep&RRL pipeline. The green and black points clearly reflect the pattern of the Gaia scanning law. More than 220 000 RR Lyrae stars are shown in the figure, of which 46 443 are in the Magellanic Clouds, 2860 are in GCs, 984 in classical dSphs (885) and ultra-faint dwarfs (99; Garofalo et al., in prep.), and 50 220 are new discoveries by Gaia. To avoid further overcrowding, we did not highlight GCs and dSphs, but refer to Figs. 45 and 46 for the most complete post-Gaia DR2 view of All-Sky RR Lyrae stars down to the Gaia faint-magnitude limit of G ~ 20.7 mag.
