| Abstract: |
We present a wavelet technique to de-noise astronomical spectra based on non-orthogonal wavelet packets and compare it to Fourier-smoothing and other wavelet-based de-noising algorithms. It is found to give better results than any other tested de-noising algorithm and is particularly successful in recovering weak signals that are practically drowned by the noise. |
