Nature of problem:
The deconvolution of experimental spectra can be reduced to a problem of least squares and solved by MINUIT  minimization routines [2,3,4].
Every peak must be a function of up to 4 parameters and their number, Np, must be in the range (1 <= Np <= 13). The first restriction is a choice of the authors and can easily be overcome, while the second is a consequence of the utilized Minuit version.
The curve to be deconvolved must not necessary be a spectrum; every curve (experimental or not) can be separated into its fundamental components.
The typical CPU time needed to perform the deconvolution on a VAX-6420 is ranging between few seconds and some minutes.
