Visibilities

fringevis(bincounts),[k]

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 $v$, wavelength scale $l$, and group delay $d$.
