凯克望远镜的NIRC2红外成像仪近期升级了一套全新的偏振观测模式。这套名为NIRC2-Pol的偏振升级将开启广泛的新天文学研究，包括系外行星、银心、活动星系核及太阳系的研究。天文偏振计需要复杂的数据处理，尤其是定量偏振测量需使用穆勒矩阵模型进行仪器偏振校准。本研究提出一款灵活、易用的开源数据处理管道设计，用于NIRC2-Pol，总结其关键步骤及当前实施的细节。
英文摘要
The Keck/NIRC2 infrared imager was recently upgraded with a new suite of polarimetric observing modes. This polarimetry upgrade (referred to as NIRC2-Pol) will open up a wide range of new astronomical studies, including investigations of exoplanets, the Galactic center, active galactic nuclei and the solar system. Astronomical polarimeters require sophisticated data reduction, especially for quantitative polarimetry requiring the use of a Mueller Matrix model for instrumental polarization calibration. This work presents the design of a flexible, user-friendly, open-source data processing pipeline intended for use with NIRC2-Pol, summarizing its key steps and details of its ongoing implementation.
