For years, users with large multi-spectra datasets (e.g., depth profiles with 100+ spectra) complained about memory crashes. Version 41 is now fully , allowing it to utilize all available RAM. This means you can fit 500 peaks simultaneously without crashing.

Run the fitting engine. The software will iteratively adjust unconstrained parameters to minimize the Chi-squared ( χ2chi squared ) residual value.
