Astrometric and spectroscopic observations of the monitorings of one period (upper plots) and 6 months (lower plots) of the S2 star, simulated with the full-GR model. For one period of monitoring we consider one week of observation at pericenter passage (blue points), 6 months of observations around the pericenter passage (red points) and 14 yr of observations for the rest of the orbit (black points). The 6 months of monitoring corresponds to the first nineteen points of the one-period run.
