The filter spectrum window

This window provides the ability to filter the current spectrum displayed in a plot.

The various options are:

• Average take the running average value over a number of positions.
• Median take the running median value over a number of positions.
• Profile smooth the values using a profile matched to typical line shapes, Gaussian, Lorentzian and Voigt.
• Spectrum smooth the values using a profile defined in another spectrum (allows you to create kernels that match some shape, rather than just the standard profiles).
• Wavelet use various wavelet filters to convert the spectrum into multi-resolution coefficients, removing a fraction of the coefficients, thus denoising the spectrum.
