论文摘要
詹姆斯·韦伯（James Webb）空间望远镜（JWST）上的中红外仪器（MIRI）具有成像，四个Coronagraph和低分辨率光谱模式。能够模拟Miri观察结果将有助于调试该仪器，并使用户熟悉代表性数据。我们设计了Miri仪器模拟器（MIRISIM），以使用Miri仪器团队开发的校准数据产品（CDP）模仿Miri成像仪和光谱仪的轨道性能。该软件包含沿光路径，包括望远镜的辐射背景和宇宙射线的探测器，切片机，扭曲和噪声源的准确表示。该软件还包括一个模块，该模块使用户能够创建天文学场景来模拟。 Mirisim是可以在命令行或Python内部运行的公开python软件包。 Mirisim的输出是将传递给Miri用户的未校准数据格式的检测图像。这些包含JWST校准管道摄入必要的元数据。
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 encorporates 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 which 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.
