sd.scantable.lag_flag - Function

5.1.2 Perform Fourier filtering on the spectra
Description

Flag the data in ’lag’ space by providing a frequency to remove. Flagged data in the scantable gets interpolated over the region. No taper is applied.

If insitu is True, or insitu is None and sd.rcParams[’insitu’] is True, the method will not return the result, but apply operation on this scantable.

It is recommended to flag edges of the band or strong signals beforehand.
