Iulian Ruxandra | RUN | Software | | New Kinematics plots (4h of stats) |
More statistics on the script written by Adrian and Valerian (first image)
Second image is a comparison between the excited states produced between 90-130 deg and 130-180 deg. Effects of angular distribution?
the kinematic line seen in the Elab vs Theta at backward angles can be observed in figure 3. Are those protons? |

A. Lemasson | OFFLINE | Software | | VAMOS Conversion HowTo |
HOW TO convert a run in VAMOS
- Do : source $HOME/GoToVamosAna
- To Convert a Run : MyVAna -d2Ar <RunNr>
- Otherwise, If you want to convert a single file : MyVAna -d2Ar -f <Infile> <OutFile>
- Output Root rile is written to : ./RootA/
If you encounter the error on Brho "Could not find the BrhoRef for the run <RunNr> ", Update the ./Calibs/ListBrho.dat file with relevant Brho for RunNr |
