5 | // Script that contains a class to draw eloss from hits, versus ADC | |
6 | // counts from digits, using the AliFMDInputHits class in the util library. | |
7 | // | |
8 | // It draws the energy loss versus the p/(mq^2). It can be overlayed | |
9 | // with the Bethe-Bloc curve to show how the simulation behaves | |
10 | // relative to the expected. | |
11 | // | |
12 | // Use the script `Compile.C' to compile this class using ACLic. | |
