How can I remove the spikes appearing in the spectra?

[rese_support]

Reflectance spectra often have spikes in the spectral regions with atmospheric water vapor after atmospheric correction.There are 3 possibilities:
- reduce the atmospheric water vapor column
- do a re-calibration ("Inflight Calibration" with reference targets)
- try the "Spectral Polishing" module (only for small-amplitude spikes).
