3.7 Flagging auto-correlations with flagautocorr

Alert: flagautocorr is still available in CASA 3.4. But tflagdata (§ 3.4) will be our new flagging task (renaming it it flagdata in CASA 3.5). We strongly recommend to use tflagdata as it is faster and the syntax will be supported in the future. tflagdata has an autocorrelation option in mode ’manual’.

The flagautocorr task can be used if all you want to do is to flag the auto-correlations out of the MS. Nominally, this can be done upon filling from the VLA for example, but you may be working from a dataset that still has them.

This task has a single input, the MS file name:

To use it, just set and go:

Note that the auto-correlations can also be flagged using tflagdata (§ 3.6) but the flagautocorr task is a handy shortcut for this common operation.
