PK_BCURVE_fit_err_method_t    


typedef int PK_BCURVE_fit_err_method_t;


This data type selects how points in the sample data are matched to the
approximating bcurve for calculating the error in the fit.   It has values:

    PK_BCURVE_fit_err_none_c      don't calculate any errors on bcurve
    PK_BCURVE_fit_err_parm_c      match sample point to point on bcurve
                                  with equal parameter
    PK_BCURVE_fit_err_closest_c   match sample point to closest point
                                  on bcurve
