The Interface Region Imaging Spectrograph (IRIS) is a NASA small explorer mission that provides high-resolution spectra and images of the Sun in the 133 – 141 nm and 278 – 283 nm wavelength bands. The IRIS data are archived in calibrated form and made available to the public within seven days of observing. The calibrations applied to the data include dark correction, scattered light and background correction, flat fielding, geometric distortion correction, and wavelength calibration. In addition, the IRIS team has calibrated the IRIS absolute throughput as a function of wavelength and has been tracking throughput changes over the course of the mission. As a resource for the IRIS data user, this article describes the details of these calibrations as they have evolved over the first few years of the mission. References to online documentation provide access to additional information and future updates.

界面区域成像光谱仪 (IRIS) 任务的仪器校准

界面区域成像光谱仪 (IRIS) 是 NASA 的一项小型探测器任务,可提供 133 – 141 nm 和 278 – 283 nm 波段的高分辨率光谱和太阳图像。IRIS 数据以校准形式存档,并在观测后 7 天内向公众提供。应用于数据的校准包括暗校正、散射光和背景校正、平场、几何失真校正和波长校准。此外,IRIS 团队已将 IRIS 绝对吞吐量校准为波长的函数,并一直在跟踪任务过程中的吞吐量变化。作为 IRIS 数据用户的资源,本文描述了这些校准的详细信息,因为它们在任务的最初几年中不断发展。
