-// AliTPCCalROC *GetCalRocPedestal(Int_t sector); - for the pedestal values
-// AliTPCCalROC *GetCalRocNoise(Int_t sector); - for the Noise values

// example for visualisation:
// if the file "PedestalData.root" was created using the above example one could do the following:
// padPedestal->MakeHisto2D()->Draw("colz"); //Draw A-Side Pedestal Information
// padNoise->MakeHisto2D()->Draw("colz"); //Draw A-Side Noise Information
