Instead of comparing signal/Noise with cleaning level 190 // one and two, we calculate 191 // - P_ped: The probability that a signal is a pedestal (using 192 // the signal height and the pedestal) For this probability the 193 // same algorithm like in kScaled is used (which is a standard 194 // cleaning which scales the noise with the mean noise of pixels 195 // with the same size) 196 // - P_sig: The probability that the signal corresponds to the pixel 197 // with the highest signal. For this probability we use the 198 // arrival time only. 199 // 200 // The cleaning now is done in levels of Probability (eg. 0.2, 0.05) 201 // The meaning of the cleaning levels is essentially the same (the same cleaning 202 // algorithm is used) but the cleaning is not done in levels of signal/noise 203 // but in level of this probability. 204 // 205 // This probability is calculated as (1-P_ped)*P_sig 206 // 207 // Example: 208 // 209 // MImgCleanStd clean(0.2, 0.05); 210 // clean.SetMethod(MImgCleanStd::kProbability); 211 // 212 // 186 213 // Member Function: SetMethod() 187 214 // ============================
