In order to run this script, the xtc file path and names should be substituted, then use commands:

Project of analysis-specific modules
...
- Define and cut the spectral regions for signal and reference band.
- Integrate in columns .Evaluate and evaluate two 1024-bin spectra, fs and fr, and their relative difference : r= 2(fs-fr)/(fs+fr).
- Put 3 spectra in the event as
ndarray<double,2>
object. - Save spectra in the text file, 1024 x 3 lines of float numbers, if necessary.
...
Module example for analysis of spectra
Functionality
- get the
ndarray<double,2>
object from the event. - do iteration over vectors and print elements for example.
Note Then users extend this module functionality depending on their goal...
Module parameters
- source
- key_in
- other parameters for analysis or accumulation of the spectrastatistics etc.
