- Detrending by smoothing the time series with the following options
- No smoothing (fft of the raw data)
- Binomial smoothing (specify sampling time and cut-on frequency)
- Polynomial smoothing (up to any degree...)
- Triangle smoothing (specify width in minutes)
- Spline interpolation

- If the data have been smoothed you can:
- Compute the absolute variations (default)
- Compute the relative variations

- Apodize the detrended of raw time series
- No apodization (default)
- Parabolic (Welsh)
- Cosine (Hanning)
- Triangular (Parzen)

- Invalid data:
- Detection by minimum and maximum values
- Replaced by zeros for the detrended time series
- Replaced by the mean of the valid data for the raw time series
- Spikes are removed if they exceed a given threshold

- The time series are normalized to take into account:
- The apodization function
- The invalid data

- Other features
- Broadcast what the routines is doing (optional)
- Return the detrended time series only (optional)
- Return the window of the time series (optional)

- Histogram plot
- Compare the histogram of input data to a normal distribution
- Compare the histogram of input data to a chi square with n dof (optional) (Needs kolmo.pro)
