G (cyan), G_BP (blue), and G_RP (red) light curves of RR Lyrae stars of different pulsation mode in the Galactic globular clusters M3 and M62 and in the Sculptor dSph galaxy (G band only), released in DR2. Gaia DR2 1454784656715455360 is located within the M3 half-light radius (r_h = 2.31 arcmin, Harris 1996), star 6029368479902370048 is within twice the r_h of M62 (r_h = 0.92 arcmin, Harris 1996). Gaia DR2 5027166723552830464 in Sculptor is a new discovery by Gaia. Only the G-band light curves are shown for Sculptor because of the low S/N of the G_BP and G_RP time-series data at the faint magnitudes of the RR Lyrae stars in this dSph galaxy. The multi-band time-series data are folded according to the period and epoch of maximum light derived by the SOS Cep&RRL pipeline. Error bars are comparable to or smaller than symbol size.
