f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	27 % is lower than the value specified in the parameter MSEVARTOL.
f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	28 % E.g. FITTOL = 1e-3, MSEVARTOL = 1e-2 will search for a fit with

f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	49 % property can be used to test the accuracy of a fit procedure. In
f0afece42f48 Import. Daniele Nicolodi <nicolodi@science.unitn.it> parents: diff changeset	50 % particular it can be tested that the spectral flatness coefficient of
