Data available
There are three set of data :
- - Mono-LST-1
- - LST+MAGIC
- - MAGIC
Monte Carlo Data
Monte Carlo data have been produced with successive productions in order to increase the node density. We asked also to have test nodes on the declination line. The figures show the present simulated nodes, to be found in
1- First production has been performed standardly with uniform training nodes on the declination line
2- Second production has been performed asking a node with with step cos(zenith)=0.04, for zenith angles > 60 deg (see here)
3- Third production has been performed in order to further increase the node density with step cos(zenith)=0.02, for zenith angles > 60 deg (see here)

4- Fourth production is based on the concept of a very dense simulation line but each node having a low statistics (see here). The idea and method have been presented in several talks (see below)

We these new RFs we have reconstruct the old MC line in order to have protons and diffuse gamma as tests:
