For the IRS: Spectral resampling is the process by which the spectral samples derived from a sampled interferogram are relocated to pre-determined wavenumber locations, thus forming spectral channels

### Assistant:

NOT_RELEVANT: For the IRS:
VARIABLE: spectral channels
CONDITION: forming
KEYWORD: thus
