Distributions of stars simulated by the Vasiliev et al. (2021) model (gray points) and RRLs from the RRLS-SGR-R22 (green points) and RRLS-SGR-SELECTION (orange points) samples, in the distance versus Λ plane. Blue and red squares represent the mean distances as a function of Λ in the leading and trailing arms, respectively, as modeled by Hernitschek et al. (2017). The SgrΛ coordinate is given in the system introduced by Vasiliev et al. (2021).
