Detected fringes from the global fringe search in AIPS for baselines to the RadioAstron satellite. The top panel shows the residual delay of the SRT, the middle panel shows the residual rate of the SRT, and the bottom panel shows the S/N of the initial FFT stage. C band solutions are marked in red and K band solutions are marked in blue. Solutions with S/N_AIPS, FFT ≥ 5.0 are marked with stars and solutions with S/N_AIPS, FFT < 5.0 are marked with dots. The dotted line shows the cutoff-value of S/N_AIPS, FFT ≥ 3.1 adopted for the second round of fringe search using narrow windows.
