Comments |
Although this script is billed as a EELS script - it should work on any intensity profile, EDS spectrum etc. These frequently consist of overlaid spectra and in the case of EELS, background fits and extracted edges. This script will extract all such slices present in the front-most spectrum and display them as stand-alone spectra.
|
System Requirements |
This script should be compatible with all recent versions of DigitalMicrograph. |

// Script to extract and display overlaid spectra. For example an EELS spectrum with a // background fitted contains the spectrum, the background and the extracted edge. // Running this script with such a spectrum front-most would display the three component // spectra as individual spectra.
