Functions

checkchflag	check flag consistancy across channels it’s able to handle ms with multiple spw/pol.
flagbywt	doesn’t really work yet (see statwt.py) performe the following procedures: 1. save current flagging 2. use statwt to recalculate weight 3. flag weightoutlier.
flagchan	flagged the channel if the data from contributing rows are partially flagged this is <unchflag> in the CASA 5 xutils
flagrow	flagged the entire row if it’s partially flagged use this with cautions and you’re removing potentially large amount of rows
getcommonfreqs	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
getfreqs	get the frequency sampling grid of one SPW in a MS, in a specified frame edge is for original grid
read_ms	Note:
rmColumns	remove columns from MS (only handle one column currently) By default, the function will check the available column names without removing any column.
