centWave results for example region 1. centWave results for example region 1. The lower part shows the same extracted ion chromatogram (277.213–277.221 m/z) as in Figure 3 and the detected chromatographic peaks from the centWave algorithm as Gaussian fits. The upper part shows the CWT coefficients on the different scales. A cross marks the scale where the peak was optimally localised. The vertical grey lines show the peak borders which were estimated from the coefficients of this scale.
