I am having two issues, I would like to write a macro to solve:
- To remove initial unwanted area from a mass plot region 2 - 2.8.
- I want to fit a Gaussian function, I tried this exp(-0.5pow((x-)/,2)), but not so appropriate. I would
like to find the yield from the  value.
Thank you for all your help.
You could try to use the fit panel…
Could I use a macro instead of the fit panel?
Sure, but using the fit panel allows to first estimate the fit parameters in an interactive way…
How about choosing a good fit function?
Same here. The fit panel has several pre-defined fit functions
