This software is currently not actively maintained. At present only the forward-folder method is included. Gold and Bayes unfolders to be included.
Install the project mandatory dependencies:
- ROOT [https://root.cern.ch/]
Make sure you have set the following environment variables to the external library installation dirs
- ROOTSYS: set to ROOT installation prefix
NB: Modify Makefile CPPFLAGS and LDFLAGS in case the dependency tools cannot be found.
To build the project:
- Clone this repository into your local $SOURCE_DIR
git clone https://github.com/PierreAugerObservatory/SpectrumUnfolder.git $SOURCE_DIR - In the project directory type:
make
Binaries will be placed in the bin/ directory and libraries in the lib/ directory.
SpectrumUnfolder --input=[path-to-inputfile] [--histoname=[data-histo-name]]
--input - Input file name containing histogram to be read (.root)
--histoname - Name of histogram with spectrum data to be unfolded (default=RecSpectrum)
