Parameters Defaults FIT windows / LEASTSQUARES POISSON ZEROES ERRANALYSIS ITERATIONS(it) 10 TIME(tt) 60 LIST NODISPLAY Purpose Perform fit of the specified function(s) to the data
List of display window names or condition numbers or # (for temporary window) defining the fit region. If omitted the fit region is defined by the fit windows. In any case only displayed data are fitted.
Selects chi-square fitting with the least squares method. This is the default. Weighting factors are derived from the symmetrized errors in y-direction.
Selects fitting according to the maximum likelihood method. With this method the y-value of each data point is assumed to follow a Poisson distribution, which is appropriate for low counting rates. Not yet implemented
Include data points with y=0 in the fit. Normally such data are not considered.
Perform an extensive analysis for the fit parameter (asymmetric) errors. Might be time consuming !
Maximum number of iterations.
Maximum amount of CPU time for a particular fit. After expiration the iteration loop is aborted. Unlimited time for tt<=0.
List fit statistics each iteration
Don't display intermediate fit curves
