• Name of the source: SNR 106.3+2.7
• Brief description of the source: Strong hadronic PeVatron candidate with TeV emission both from the head and the tail of the SNR
• Reference coordinated:

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.

- First production has been performed standardly with uniform training nodes on the declination line

- Second production has been performed asking a node with with step cos(zenith)=0.04, for zenith angles > 60 deg (see here)

- 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)

We asked also to have test nodes on the declination line. The figures show the present simulated nodes, to be found in
