+Comment from 22 Dec 2008
- //enum { kMaxRows = 16, kMaxTbins = 24, kMaxCols = 144};
+The structure of the Index was changed. Now no Tbin is saved anymore,
+only RC combination are saved! (reasons see below)
- private:
+For the readout, all tbins for a RC combination must be read out to find
+the time bin of signal > 0.
- Int_t fDet; // det number
- Int_t fLayer; // aka plane - position in the full TRD
- Int_t fStack; // aka chamber - position in the full TRD
- Int_t fSM; // super module - position in the full TRD
+THE WRITING PROCEDURE:
+AddIndexTBin is now obsolate, use AddIndexRC instead as AddIndexTBin will
+be deleted in future.
- protected:
+example that gives exactely the same output as before:
+as it was:
+ AliTRDSignalIndexes *indexes;
+ AliTRDarrayADC *Signal; //or AliTRDarraySignal *Signal;
+ if(Signal->GetDataB(row, col, time)>0)
+ indexes->AddIndexTBin(row, col, time);
- TArrayI *fIndex; //! monitor active pads and tbins
+as it should be from no on:
+ AliTRDSignalIndexes *indexes;
+ AliTRDarrayADC *Signal; //or AliTRDarraySignal *Signal;
+ if(Signal->GetDataB(row, col, time)>0)
+ indexes->AddIndexRC(row, col);
- Int_t fPositionRow; // position in the index - jumps by 1 + 1 + fNtbins
- Int_t fPositionCol; // position in the index - jumps by 1 + 1 + fNtbins
- Int_t fPositionTbin; // position in the tbin - goes from 0 to fNtbins
- Int_t fLastRow; // to keep track what is the RC combination
- Int_t fLastCol; // to keep track what is the RC combination
- Int_t fLastTbin; // to keep track what is the Tbin - will catch if raw data bogus
- Int_t fNrows; // number of rows in the chamber
- Int_t fNcols; // number of cols in the chamber
- Int_t fNtbins; // number of tbins in the chamber
+THE READING PROCEDURE:
+In most cases you can leave anything as it is.
+See more in the example.
- Int_t fMaxLimit; // max number of things in the array = nrow * ncol * ntime + nrow * ncol * 2
+example:
+as it was:
+ AliTRDSignalIndexes *indexes;
+ AliTRDarraySignal *Signal;
+ while(indexes->NextRCTbinIndex(row, col, time))
+ {...}
- Bool_t fResetCounters; // reset counter status
+as it should be from no on to get the exactely the same output as before:
+ AliTRDSignalIndexes *indexes;
+ AliTRDarraySignal *Signal;
+ while(indexes->NextRCTbinIndex(row, col, time))
+ if(Signal->GetData(row, col, time)>0)
+ {...}
- Bool_t fHasEntry; // kTRUE flag if we have an entry
+as it should be idealy:
+ AliTRDSignalIndexes *indexes;
+ AliTRDarraySignal *Signal;
+ for(time = 0; time < Ntime; time++)
+ while(indexes->NextRCIndex(row, col, time))
+ if(Signal->GetData(row, col, time)>0)
+ {...}
- ClassDef(AliTRDSignalIndex,1) // Data container for one TRD detector segment
-};

-#endif
+REASON OF THE CHANGES:
+
+The array saved the information nicely, but it turned out that sorting
+the array by column would have many benefits.
+I.e. it is crucial for fivePadClusters and it if much faster to allocate.
+But the sorting is not fast if the tbin is also saved.
+Moreover the tbin information was alsmost useless because,
+whenever an RC index existed, many of the possible tbins where used.
