Baseline using IGOR Pro 5.05 software

Share icon

I am having problem with drawing a baseline for data that I collected using X-ray Photoelectron spectroscopy. I did it in 2006 but could not remember the code I used for setting a baseline for my data. I need to draw the baseline before fitting the curves through Analysis - Packages- Multipeak fitting etc.

Can someone help me on what to do? I attach the data.

Thank you. -XPS data.xls (841.5 KB)
Did you perhaps use the Technical Note #20 experiment to remove the baseline?

Use Igor to open the "Peak Measurement" experiment file in:

Igor Pro Folder/Technical Notes/Igor Tech Notes/TN 020 Peak Measurement/

Is your baseline something other than constant, line, or cubic? If constant, line or cubic will do, then Multipeak Fit will do the fit to peaks and baseline all in one, and you don't need to pre-subtract a baseline.
