Observed contrast loss at 2.2 μm versus off-axis separation for the ATs. The three curves indicate the typical contrast loss for different seeing and isoplanatic angle values as expected from atmospheric turbulence following Elhalkouj et al. (2008). Crosses represent data from GRAVITY Wide observations with the prototype implementation in November 2019, while circles represent data from GRAVITY Wide commissioning in December 2021. Seeing and isoplanatic angle values are measured by the MASS-DIMM at the Paranal observatory, and are defined at 500 nm.
