Residuals of the Δα (top) and Δδ (bottom) positions from the orbit of θ1 Ori C2. The blue circles represent the residuals of GRAVITY data and their respective uncertainties. The gray squares are the residuals from non-GRAVITY observations. The rms of the GRAVITY residuals is 0.07 mas for Δα, and 0.05 mas for Δδ.
