论文摘要
NASA的下一个旗舰任务Nancy Grace Roman Space望远镜是一款2.4米的天文台，可在2027年5月之前发射。罗马具有两种乐器：宽场成像器和Coronagraph仪器。罗马的Coronagraph是一项技术演示，将直接成像的当前功能推向较小的对比度（$ \ sim $ 10 $^{ - 9} $）和内部工作角度（3〜 $λ$/d）。为了达到这一高度，必须校准罗马冠冕数据，以消除尽可能多的潜在错误来源。在这里，我们介绍了Nancy Grace Roman Space Coronagraph仪器观察校准计划的详细概述，包括识别潜在的误差源以及如何通过天上的校准来减轻它们。
NASA's next flagship mission, the Nancy Grace Roman Space Telescope, is a 2.4-meter observatory set to launch no later than May 2027. Roman features two instruments: the Wide Field Imager and the Coronagraph Instrument. Roman's Coronagraph is a Technology Demonstration that will push the current capabilities of direct imaging to smaller contrast ratios ($\sim$10$^{-9}$) and inner-working angles (3~$λ$/D). In order to achieve this high precision, Roman Coronagraph data must be calibrated to remove as many potential sources of error as possible. Here we present a detailed overview of the Nancy Grace Roman Space Telescope Coronagraph Instrument Observation Calibration Plan including identifying potential sources of error and how they will be mitigated via on-sky calibrations.
