Path to the necessary header files and libraries must be set by the user on a machine-by-machine basis in the premake5.lua file. Set the ROOTIncludepath and ROOTLibpath to match your install. An easy way to check for the paths on a unix system is through the root-config tool. root-config --cflags has the include path (the path after -I) and root-config --glibs has the lib path (after -L). If you do not have ROOT installed, you will not be able to compile RootPlot, and you will not be able to use the generic `make` command, which will try to build all executables. Instead use `make Mask` or `make DetectEff` (or `make config=release Mask`, etc). ## Running MASK By default MASK is capable of simulating reactions of up to three steps.

Here is For decays, a specific angular distribution can be given as input as a text file with values of coefficiencts of a Legendre polynomial series. Examples can be found in the `./etc` directory, including an isotropic case. It is assumed that the decays in the center-of-mass frame are isotropic in phi (i.e. m=0). Decay1 corresponds to the first decay, if there are multiple steps, Decay2 to the second. If there are no decays, these parameters are not used (or if only one decay, Decay2_AngularMomentum is not used). The input file requires that the user include target information, which will be used to calculate energy loss for all of the reactants and reaction products. The target can contain layers, and each layer can be composed of a compound of elements with a given stoichiometry. If the user wishes to not include energy loss in the kinematics, simply give all target layers a thickness of 0. Note that more layers and more thickness = more time spent calculating energy loss. These energy loss methods are only applicable for solid targets, and should not be applied to gas or liquid targets. Energy loss calculations have a stated uncertainty of approximately five percent. -The default MASK program includes a calculation of SABRE efficiency, whose methods are contained in the SabreEfficiency and SabreDetector classes. This can be disabled by modifying the main.cpp file appropriately. It also has the classes for calculating ANASEN efficiency. More detector classes can be added following the format outlined by these two examples. - -In the input file the user also has the option to select to save the ROOT tree of the simulated data and the default plots.
