Ratio of improvement, found by taking the ratio of an idealised integrator on VLT/SPHERE to a recursive spatial-temporal predictor (s1t10) phase variance as calculated from the last 5 s of data, as a function of coherence time. The size of the markers indicates the MASS-DIMM seeing conditions at the time of observation. The average ratio of improvement is 5.1 when comparing the prediction to the real VLT/SPHERE residuals. When looking at the idealised VLT/SPHERE, we find an average ratio of improvement of 2.0 in wavefront variance reduction.
