Removing atmospheric turbulence from ground-based astrometry with fast correlation function measurements
Daniel C. H. Gomes, Gary M. Bernstein, Claire-Alice Hébert
We present a code that removes of the variance in astrometric measurements caused by atmospheric turbulence, by using Gaussian process regression (GPR) to interpolate t…
