Detailed Description

test of the tpc merging using AliRunDigitizer and TPC Hits2Digits, Hits2SDigits and SDigits2Digits macros preparation 0. make 2 directorys - ev1 and ev2 1.make hits, digits,sdigits and sdigits-digits in both directories 1.a galice -b -q grun.C and produce hits 1.b. cp galice.root galice.root.hits 1.c run AliTPCHits2Digits.C 1.d cp galice.root galice.root.digits 1.e copy back cp galice.root.hits galice.root 1.f run AliTPCSDigits2Digits.C 1.g cp galice.root galice.root.sdigits 1.h run AliTPCSDigits2Digit.C 1.i cp galice.root galice.root.dig2

  1. cp ev1/galice.root/galice.root.sdigit galice.root
  2. load this macro and run testmerge()
  3. run test function bellow to compare merged digits with original one
  4. to be noticed output ftom testx() function - should be bigger than noise because in proces of digitisation we use different seed of random numbers for diffusion and gas gain -anyway in place where we have the signal should occur the signal in both casses
    • only the amplitude should be different - by factor of sqrt

Int_t  amp1,
Int_t  amp2 

Definition at line 121 of file AliTPCTestMerge.C.

void drawmerged ( Int_t  sec,
Int_t  row,
Int_t  x1 = -1,
Int_t  x2 = -1,
Int_t  y1 = -1,
Int_t  y2 = -1 

if you think that there is memory leak - you are tru but othervise graphic doesn't work sec=0; row =0;
