+Instruction - how to use that:\r
+There are two macros prepared. One is for preparing clusters from MC \r
+samples: FindKrClusters.C. The output is kept in TPC.RecPoints.root.\r
+The other macro is prepared for data analysis: FindKrClustersRaw.C. \r
+The output is created for each processed file in root file named adc.root. \r
+For each data subsample the same named file is created. So be careful \r
+do not overwrite them. \r
+\r
+Additional selection criteria to select the GOLD cluster\r
+Example:\r
+// open file with clusters\r
+TFile f("Krypton.root");\r
+TTree * tree = (TTree*)f.Get("Kr")\r
+TCut cutR0("cutR0","fADCcluster/fSize<100"); // adjust it according v seetings - \r
+TCut cutR1("cutR1","fADCcluster/fSize>7"); // cosmic tracks and noise removal\r
+TCut cutR2("cutR2","fMax.fAdc/fADCcluster<0.2"); // digital noise removal\r
+TCut cutR3("cutR3","fMax.fAdc/fADCcluster>0.01"); // noise removal\r
+TCut cutS1("cutS1","fSize<200"); // adjust it according v seetings - cosmic tracks\r
+TCut cutAll = cutR0+cutR1+cutR2+cutR3+cutS1;\r
