nsb2: an open source tool for simulating Imaging Atmospheric Cherenkov Telescope Night Sky Background — •Gerrit Roellinghoff1, Samuel Spencer2,1, and Stefan Funk1 for the H.E.S.S. collaboration — 1Friedrich-Alexander-Universität Erlangen-Nürnberg, Erlangen Centre for Astroparticle Physics, Nikolaus-Fiebiger-Str. 2, 91058 Erlangen, Germany — 2Department of Physics, University of Oxford, Keble Rd, Oxford OX1 3RH, United Kingdom
As a result of being exposed to the night sky, Imaging Atmospheric Cherenkov Telescopes (IACTs) are sensitive to background illumination; all sources of illumination that are not Cherenkov light. This Night Sky Background (NSB) limits the operational time of IACTs, introduces systematic uncertainty and is a source of Data/Monte-Carlo mismatch. Building on software previously developed for H.E.S.S., we present an open source tool for the pixel-wise prediction of NSB in IACTs, simulating contributions from a variety of sources, such as starlight, moonlight and atmospheric glow. It allows for the computationally efficient prediction of NSB rates for a variety of IACT types, thus improving on Data/Simulation mismatch and enabling users to plan observations for IACTs during partial moonlight observations.
