Message:

chan_avg_limit parameter has been added to auto_poly_baseline method. It is passed to linefinder and determines whether to search for broad weak lines to exclude them from the baseline solution. Default value is 1, which means no search for such lines.

    12421243                        keep it large as only strong lines affect the
    12431244                        baseline solution.
     1245            chan_avg_limit: 
     1246                        a maximum number of consequtive spectral channels to
     1247                        average during the search of weak and broad lines.
     1248                        The default is no averaging (and no search for weak
     1249                        lines). If such lines can affect the fitted baseline
     1250                        (e.g. a high order polynomial is fitted), increase this
     1251                        parameter (usually values up to 8 are reasonable). Most
     1252                        users of this method should find the default value
     1253                        sufficient.
    12441254            plot:       plot the fit and the residual. In this each
    12451255                        indivual fit has to be approved, by typing 'y'
