16 May 2013 iSignal 2.8 Interactive smoothing, differentiation, peak sharpening and measurement of time-series signals. Author: Tom O'Haver

Version 2.8 has an improved frequency Spectrum function that remains active when changing the smoothing, differentiation, and other functions, allowing you to see the effect on the frequency spectrum immediately. Press Shift-S again to return to the normal mode.

Ben, not so far, but it's an interesting possibility. Can you give me an example of a 2D data set with peaks and the kind of information your would like to obtain from a 2D peak fitter program?

Version 9.2, uploaded today, has bug fixes; fixed-position Gaussians (shape 16) and fixed-position Lorentzians (shape 17); adds a peak shape selection menu (activated by the '-' key).
21 Feb 2013 Peak Fitter Command-line peak fitter for time-series signals. Version 3.6: February, 2013. Author: Tom O'Haver

Version 3.6: February, 2013. Addition of fixed-position Gaussian (shape 16) and fixed-position Lorentzian (shape 17). See example 19 on http://terpconnect.umd.edu/~toh/spectrum/InteractivePeakFitter.htm.

So I guess It's about that that I add such a capability. I'll work on it and try to have something together in a few days.

Hi Tom,

Thanks for your reply!

What do you think some basic 2D shape, such as Gaussian, elongated Gaussian (Gabor), high peak and (approximately) pole with half sphere on the top?

I will send you an example data later. The data belong to my old project.

Thanks in advance!
Ben

Do you have a 2D version of this peak fitter?

Tom, it works very well for me. Thank you!
The start and the end position of the peaks would also help me… the definition of 1% of the peak amplitude would be great.
