AI 中文摘要
詹姆斯·韦伯空间望远镜（JWST）搭载的近红外相机（NIRCam）能够探测到视星等约31等的小型天体。但NIRCam的复杂性会在图像获取过程中引入多种细微效应，进而影响从图像中提取的天体测量信息。本文简要总结这些特性，并提供从NIRCam图像中提取有效天体测量位置的基础信息。
英文摘要
The James Webb Space Telescope (JWST), with its near-infrared imager NIRCam, is capable of obtaining detections of small bodies down to what would correspond to a visual magnitude of about 31. However, the complexity of NIRCam introduces multiple subtle effects in the way the images are obtained, and they in turn affect the astrometric information that can be extracted from the images. In the following, we very briefly summarize these peculiarities, and provide some basic information on how to extract meaningful astrometric positions from NIRCam images.
