摘要:

1640项目是一个高对比度近红外仪器,通过积分场摄谱仪与Lyot日冕仪和高阶自适应光学系统的独特组合探测附近恒星的附近。非凡的数据减少的需求,类似的几个新的系外行星成像仪器将在不久的将来面临的,已经满足了本文所述的新的软件算法。Project 1640 Data Cube Extraction Pipeline(PCXP)可自动将3.8*10^4紧密封装的粗采样光谱转换为数据立方体。我们实现了一个强大的经验模型的摄谱仪焦平面几何配准检测器图像在亚像素精度,并映射立方体提取。我们证明了我们的能力,准确地检索源光谱的基础上观察土星的卫星土卫六。

英文摘要:

Project 1640 is a high contrast near-infrared instrument probing the vicinities of nearby stars through the unique combination of an integral field spectrograph with a Lyot coronagraph and a high-order adaptive optics system. The extraordinary data reduction demands, similar those which several new exoplanet imaging instruments will face in the near future, have been met by the novel software algorithms described herein. The Project 1640 Data Cube Extraction Pipeline (PCXP) automates the translation of 3.8*10^4 closely packed, coarsely sampled spectra to a data cube. We implement a robust empirical model of the spectrograph focal plane geometry to register the detector image at sub-pixel precision, and map the cube extraction. We demonstrate our ability to accurately retrieve source spectra based on an observation of Saturn's moon Titan.
