Function. Return complex visibility for bincounts. The parameter k selects a particular baseline, i.e. fringe frequency. Examples: v=fringevis(bincounts(*,0,*),7), which returns the (complex) visibility of channel 1, and the baseline with the frequency number 7. If no sub-array of bincounts is selected, then the returned visibility array has the same dimensions as the input, minus the bin index.fringevissq(bincounts_real),[k,n]
Function. Return the (averaged) squared visibility amplitude for bincounts. The parameter n selects how many samples will be averaged.visrotate(v, l, d)
Function. Return rotated complex visibility for input visibility , wavelength scale , and group delay .
