摘要:

美国宇航局的下一个旗舰任务,南希格雷斯罗马太空望远镜,是一个2.4米的天文台,将不迟于2027年5月发射。Roman配备了两种仪器:宽视场成像仪和日冕仪。Roman的Coronagulum是一项技术演示,将直接成像的当前功能推向更小的对比度($\sim$ 10 $^{-9}$)和内部工作角度(3~ $λ$ /D)。为了达到这种高精度,罗马日冕数据必须进行校准,以消除尽可能多的潜在误差源。在这里,我们提出了一个详细的概述南希格雷斯罗马空间望远镜日冕仪观测校准计划,包括确定潜在的误差来源,以及如何通过对天空的校准来减轻。

英文摘要:

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.
