19 | // Implementation of the TPC Kr cluster class | |
20 | // | |
21 | // Origin: Adam Matyja, INP PAN, adam.matyja@ifj.edu.pl | |

25 | Instruction - how to use that: | |
26 | There are two macros prepared. One is for preparing clusters from MC | |
27 | samples: FindKrClusters.C. The output is kept in TPC.RecPoints.root. | |
28 | The other macro is prepared for data analysis: FindKrClustersRaw.C. | |
29 | The output is created for each processed file in root file named adc.root. | |
30 | For each data subsample the same named file is created. So be careful | |
31 | do not overwrite them. | |
32 | ||
557ab431 | 33 | Additional selection criteria to select the GOLD cluster |
34 | Example: | |
35 | // open file with clusters | |
36 | TFile f("Krypton.root"); | |
37 | TTree * tree = (TTree*)f.Get("Kr") | |
38 | TCut cutR0("cutR0","fADCcluster/fSize<100"); // adjust it according v seetings - | |
39 | TCut cutR1("cutR1","fADCcluster/fSize>7"); // cosmic tracks and noise removal | |
40 | TCut cutR2("cutR2","fMax.fAdc/fADCcluster<0.2"); // digital noise removal | |
41 | TCut cutR3("cutR3","fMax.fAdc/fADCcluster>0.01"); // noise removal | |
42 | TCut cutS1("cutS1","fSize<200"); // adjust it according v seetings - cosmic tracks | |
43 | TCut cutAll = cutR0+cutR1+cutR2+cutR3+cutS1; | |
44 | This values are typical values to be applied in selectors | |
