ism3d.uvhelper.ms.getcommonfreqs(vis_list, spw_list, edge_list=None, frame='LSRK', chanbin=2)

edge_list: for each vis, we exclude some edge channels for evluation as they might be flagged in pipeline chanbin: the channel width will be chanbin*max(chanwidth among vis_list) output freqgrid will be covered by all vis_list fgrid: freqeuncy grid df: frequency resolution
