The AliTPCCalibCE class is used to get calibration data from the Central Electrode using laser runs.

The information retrieved is

Overview:

  1. Working principle
  2. User interface for filling data
  3. Stored information

I. Working principle

Raw laser data is processed by calling one of the ProcessEvent(...) functions (see below). These in the end call the Update(...) function.

At the end of each event the EndEvent() function is called

After accumulating the desired statistics the Analyse() function has to be called.

II. User interface for filling data

To Fill information one of the following functions can be used:

It is also possible to merge two independently taken calibrations using the function

example: filling data using root raw data:

 
 void fillCE(Char_t *filename)
 {
    rawReader = new AliRawReaderRoot(fileName);
    if ( !rawReader ) return;
    AliTPCCalibCE *calib = new AliTPCCalibCE;
    while (rawReader->NextEvent()){
      calib->ProcessEvent(rawReader);
    }
    calib->Analyse();
    calib->DumpToFile("CEData.root");
    delete rawReader;
    delete calib;
 }
 

III. What kind of information is stored and how to retrieve it

III.1 Stored information

III.2 Retrieving information

example for visualisation:

  //if the file "CEData.root" was created using the above example one could do the following:
  TFile fileCE("CEData.root")
  AliTPCCalibCE *ce = (AliTPCCalibCE*)fileCE->Get("AliTPCCalibCE");
  ce->GetCalRocT0(0)->Draw("colz");
  ce->GetCalRocRMS(0)->Draw("colz");

  //or use the AliTPCCalPad functionality:
  AliTPCCalPad padT0(ped->GetCalPadT0());
  AliTPCCalPad padSigWidth(ped->GetCalPadRMS());
  padT0->MakeHisto2D()->Draw("colz");       //Draw A-Side Time0 Information
  padSigWidth->MakeHisto2D()->Draw("colz"); //Draw A-Side signal width Information

  //display event by event information:
  //Draw mean arrival time as a function of the event time for oroc sector A00
  ce->MakeGraphTimeCE(36, 0, 2)->Draw("alp");
  //Draw first derivative in local x from a plane fit as a function of the event time for oroc sector A00
  ce->MakeGraphTimeCE(36, 0, 0, 1)->Draw("alp");
