Does anyone here know where I can find the actual position versus time data for the orbit of the star S2 around the supermassive black hole Sagittarius A*? I have tried googling it with all possible queries imaginable yet I cannot get the tabulated data. It must exist because I have seen it plotted. I can't believe it is hidden behind a pay wall. I thought the data would be easy to find, bit it isn't. I just thought it would be fun to calculate the motion and overlay the calculation with the data.

For anyone who might be interested, I think I have found the data, see here:
