\subsection{Dataset} \section{Dataset}  Although a number of orbital and ground-based experiments and observatories exist to study the sky in $\gamma$ rays (such as HESS, Fermi/\textit{LAT}, MAGIC \& VERITAS to name a few examples), for which this work would be relevant, the aspects of the study based on true data make use of the 5-year data set from Fermi/\textit{LAT}. This is due to the good sky and galactic plane coverage at these high energies, near-uniform exposure and the large available dataset for which extensive source catalogs [reference 1FHL and 2FGL..., etc] and galactic diffuse background models have already been published, against which the separation methods can be tested.  The 5-year LAT data is used within a specified energy band between 10 and 500 GeV, covering much of the region of relevance at the cross-over of GeV and TeV studies in a well-defined and understood manner. The cosmic-rays detected for this dataset above a given lower energy cut-off are illustrated in Figure 2, for which the steep fall-off in higher-energy detections typical of GeV and TeV studies is evident.
