Hi everybody,
I am trying to deconvolute peak from experimental data.
I have a power (mW) as a function of the temperature and I have two peaks overlapping (examples attached). I woul like to deconvolute them but I am not able to find a ay to do so.
Any suggestions?
Thanks in advance.

I wonder if "deconvolution" is really what we are looking for here. Somewhere I interpret the request to separate that curve into two single peak curves. A simple fit should do the job, now the question is what type of function is the most appropriate

For the case of fitting 2 parameterized peak-functions and a background to the observations one might also have to model the point-spread of the instrument with a convolution-operation anyways. So in some sense it will still have elements of deconvolution in the solution.

Have a look at the help and documentation of deconvblind. If you make sure that the curve you want to deconvolve and the point-spread function both are column-arrays of row-arrays it should work. But deconvolution is a tricky operation where noise-amplification and ringing (Gibbs) rapidly put a limit of how far one can get.
