216 = "Q" Quiet mode (minimum printing)
217 = "V" Verbose mode (default is between Q and V)
218 = "B" Use this option when you want to fix one or more parameters
219 and the fitting function is like "gaus","expo","poln","landau".
220 = "R" Use the Range specified in the function range
221 = "N" Do not store the graphics function, do not draw
222 = "0" Do not plot the result of the fit. By default the fitted function
223 is drawn unless the option"N" above is specified.
224 = "+" Add this new fitted function to the list of fitted functions
225 (by default, any previous function is deleted)
226 = "C" In case of linear fitting, not calculate the chisquare
227 (saves time)
228 = "F" If fitting a polN, switch to minuit fitter
229 = "ROB" In case of linear fitting, compute the LTS regression
230 coefficients (robust(resistant) regression), using
231 the default fraction of good points
232 "ROB=0.x" - compute the LTS regression coefficients, using
233 0.x as a fraction of good points
