Hi,
If you really want to understand it please go to a directory /pandaroot/sds/SdsDigi and open this class PndSdsCalcStrip.cxx then you will find there are many statement like (for example):
if (fVerboseLevel > 2){
std::cout<<" part of last strip : "<<(nuOut-prevOut)<<std::endl ;
std::cout<<" charge : "<<Q2<<std::endl ;
std::cout<<" end of previous strip : "<<prevOut<<std::endl ;
}
so when you will choose verboselevel greater than two than the below cout statement will be show the details of what is happening at the time of execution of macro. so It gives the detailed information of what is happening at the time of running of macro.
