This software allows to correct the small shifts occuring at some of the transitions between different gratings and between the 2 detectors.

After unziping and launching the software you have to perform the following steps:

• Choose your file or set of files
• Define its type among the 4 proposed
• Provide the list of breakpoints where the shifts occurs, and the range assumed to be the reference
• Run the correction (it found the multiplicative factors for each range that best interpolate the derivative at the breakpoints)
• Visualize the results and possibly adjust manually the correction factors
• Save the results and possibly the correction factors
