Description
In ground-based gamma-ray astronomy, discoveries and measurements are often challenged by systematic uncertainties of the applied Instrument Response Functions. In most cases, both existing and planned future instruments rely on pre-generated simulations, where the actual observation and detector conditions are taken into account only to a certain, limited degree. Furthermore, they often assume a simplified geometry of the detector response, leading to even larger systematic uncertainties.
Over the last years, an alternative scheme of simulations that are custom-tailored to the observation conditions and detector settings (Run-Wise Simulations, RWS) has been utilized by the H.E.S.S. collaboration and played a key role in several high-impact results.
In this contribution, we are going to present how RWS can be exploited to reduce systematic uncertainties, increase the sensitivity for detecting faint sources, and thus open up new science cases.
