Separation between S62 and Sgr A* obtained from imaging runs in which S62 was modeled as point source with a Gaussian position prior.

Notes. The epoch is computed as mean over all exposures used for the image. For each night we performed ten GR runs with varying random seeds and combined the samples from all runs into an estimate of the S62 position and its standard deviation. We note that the standard deviation only accounts for the statistical position uncertainty, but not for any systematic error.
