Abstract: ABSTRACT The Mid-Infrared Instrument (MIRI) on the James Webb Space Telescope (JWST), has imaging, four coronagraphs, and both low and medium resolution spectroscopic modes. Being able to simulate MIRI observations will help commissioning of the instrument, as well as get users familiar with representative data. We designed the MIRI instrument simulator (mirisim) to mimic the on-orbit performance of the MIRI imager and spectrometers using the Calibration Data Products (CDPs) developed by the MIRI instrument team. The software incorporates accurate representations of the detectors, slicers, distortions, and noise sources along the light path including the telescope’s radiative background and cosmic rays. The software also includes a module that enables users to create astronomical scenes to simulate. mirisim is a publicly available python package that can be run at the command line, or from within python. The outputs of mirisim are detector images in the same uncalibrated data format that will be delivered to MIRI users. These contain the necessary metadata for ingestion by the JWST calibration pipeline.
