5bb5d1f6 | 6 | * @brief Script to visualise the dN/deta for pp and PbPb |
e1f47419 | 7 | * |
ffca499d | 8 | * This script is independent of any AliROOT code - and should stay |
9 | * that way. | |
10 | * | |
5bb5d1f6 | 11 | * The script is <emph>very</emph> long - sigh - the joy of drawing |
12 | * things nicely in ROOT | |
