Optimal FFT size to perform signal filtration as characterised by the standard deviation of the group delay estimates obtained after fringe-fitting as a function of the spectral resolution used at correlation. Spectral resolution ranges from 210 = 1024 to 221 = 2 097 152 points. Baselines T6-Sv, T6-Mc, Sv-Mc.
