Non-aligned spectra
When aligning the spectra by velocity or frequency (SET ALIGN
VELOCITY|FREQUENCY), the input channels may not be aligned with the
output ones (because of different resolutions or different abscissae
at reference channels). A resampling must be performed in these cases.
Fig.
shows a generic example where the channels have
different size and are not aligned.
