Astrometry (left) and light curves (right) of the hot spot – jet model with two values for the quiescent state corresponding to no quiescent (dashed lines) and the with quiescent state (full lines). In shades of blue, the hot spot has a nearly constant emission (t_σ ≫ t_orbit). The effect of beaming is reflected in the light curves. In shades of red, the hot spot has a Gaussian time emission with t_σ = 30 min. The parameters of the hot spot are listed in Table 2. We synchronized the beaming and intrinsic maximum of the Gaussian modulation. The black, blue, and green dots in the left panels represent the position of Sgr A*, the jet centroid, and the disk centroid, respectively.
