Isolated neutron stars are powerful gamma-ray emitters as detected in previous analysis and observations. The detection of the Crab Pulsar by MAGIC end VERITAS opens a new avenues linked, possibly, to acceleration site from the neutron star. Thus, the researchers have planed to simulated pulsed emission from Crab-like objects, either isolated or embedded in their Pulsar Wind Nebulae to test the capability of the software to disentangle the pulsed emission from the continuum one.
