**** CAUTION: Fitting was interrupted. You can't fit with x-errors only. Please specify the y-errors first. Not enough memory. Minimize Maximize Minimized : Maximized : Invalid input data for fitting. Recursive fitting not allowed. **** CAUTION: some of the parameter values obtained in the fit are not allowed by this function. **** CAUTION: one parameter reached its limit during fitting. **** CAUTION: ^0 parameters reached their limits during fitting. The fitting range of '^0' is not within the parameters limits. The initial parameter set was the best one. **** CAUTION: Some errors were equal to zero. **** CAUTION: Maximizing or minimizing was interrupted. There is nothing to vary. You should make some function parameters active, or check the ‘Vary X’ option. **** CAUTION: Fitting was interrupted. The parameter errors are meaningless if chi squared did not reach a minimum! Interpret these results with caution! This fit did not change any parameter. Not enough data points for fitting all parameters. There are no active parameters. This function cannot be used for curve fitting. There is no data to fit. A singularity occurred. Fitting could not be completed. A singularity occurred. Fitting was not possible. Some error values are not defined. The starting value for '^0' (^1) is outside the fitting range. Invalid fitting range for '^0'.
