5* *
6* AliLHCData: summary of the LHC related information from LHC DIP. *
7* Created from the TMap provided by the AliLHCReader with optional beginning *
8* *
9* The data are (wrapped in the AliLHCDipValT): *
10* made of TimeStamp (double) and array of values *
11* *
12* Multiple entries for each type of data are possible. To obtaine number of *
13* records (with distinct timestamp) for give type od records use: *
14* int GetNBunchConfigMeasured(int beam) (with beam=0,1) etc. *
15* *
16* To get i-th entry, use brec= AliLHCDipValI* GetBunchConfigMeasured(bm,i); *
17* Note: exact type of templated AliLHCDipValT pointer depends on the record *
18* type, concult getters to know it. *
19* *
20* Then, once the pointer is obtained, details can be accessed: *
21* int nBunches = brec->GetSize(); *
22* for (int i=0;i<nBunches;i++) printf("Bunch#%d: %d\n",i,(*brec)[i]); *
23* *
24* ATTENTION: Bunch RFBucked is NEGATIVE for bunches interacting at IR2 *
