How to subtract spectra from spectra
WebPowerful Spectrum Calculator: allowing for various mathematical operations on spectra and even on 3D spectra, with intuitive hand calculator design. Interactive Subtraction: important tool to compensate e.g. for the spectral contribution of solvents, matrix materials, substrates etc. by comfortable interactive subtraction with adjustable ... WebAt the end I settled on using a median filter from scipy (medfilt) and with a high enough kernel it removed the spikes completely. The problem on my specutils implementation was that I needed to exclude the peaks in the spectrum window by doing this, althought I found this too hard to implement on 100-120 data measurement I had:

WebFeb 14, 2016 · Hence, we need to subtract the continuum. This is usually done by fitting some functional form to the continuum (e.g. a straight line or a second order polynomial), substract this fit from the spectrum, and finally integrate from one side of the line to the other in the resulting "continuum-subtracted spectrum".
