论文摘要

詹姆斯·韦伯(James Webb)太空望远镜的近红外成像仪和无频谱仪(JWST-NIRISS)驾驶了7洞非冗余面具(NRM),这是太空中的第一个此类干涉仪,在3-5 \ micron〜evavellength中运行,而$ \ simeq 4 $ agnitudes则在W2中亮相。我们描述了Niriss Aperture掩盖干涉法(AMI)模式,以帮助潜在的观察者了解其潜在的原理,呈现一些样本科学案例,解释其操作性观察策略,表明如何通过数据模拟开发AMI建议,以及如何分析AMI数据。我们还提出了委托Ami的关键结果。由于盟军内核相成像(KPI)技术受益于AMI操作策略,因此我们还涵盖了Niriss KPI方法和分析技术,包括新的用户友好的KPI管道。 Niriss KPI的亮度为$ \ simeq 8 $ W2幅度。 AMI(和KPI)实现了$ \ sim 70 $ mas的内部工作角度,在$ \ sim 400 $ mas nircam内部工作角度内,其圆形coculter coronagraph在可比较的波长处。

The James Webb Space Telescope's Near Infrared Imager and Slitless Spectrograph (JWST-NIRISS) flies a 7-hole non-redundant mask (NRM), the first such interferometer in space, operating at 3-5 \micron~wavelengths, and a bright limit of $\simeq 4$ magnitudes in W2. We describe the NIRISS Aperture Masking Interferometry (AMI) mode to help potential observers understand its underlying principles, present some sample science cases, explain its operational observing strategies, indicate how AMI proposals can be developed with data simulations, and how AMI data can be analyzed. We also present key results from commissioning AMI. Since the allied Kernel Phase Imaging (KPI) technique benefits from AMI operational strategies, we also cover NIRISS KPI methods and analysis techniques, including a new user-friendly KPI pipeline. The NIRISS KPI bright limit is $\simeq 8$ W2 magnitudes. AMI (and KPI) achieve an inner working angle of $\sim 70$ mas that is well inside the $\sim 400$ mas NIRCam inner working angle for its circular occulter coronagraphs at comparable wavelengths.
