论文摘要
Liger是W. M. Keck天文台的第二代近红外成像仪和整体磁场（IFS），它将利用Keck All-Sky Precision Precision Precision Adiptive-Optics（KAPA）系统的功能。 Liger在0.81μm -2.45μm的波长范围内运行，并利用切片机和列式阵列IFS IF具有不同空间板尺度和视野不同的视野，从而使天文学家可用数百种模式。由于Slicer和Lenslet IFS模式的原始数据格式的复杂性很高，因此必须与数据减少系统（DRS）一起设计Liger，这将实时减少仪器的数据并将科学准备的数据提供给观察者。 DRS将减少RAW Imager和IF从读取系统中的框架，并通过适用于IFS数据显示的自定义快速外观可视化工具提供2D和3D数据产品。 DRS将为凯克天文台档案馆（KOA）提供简化的数据，并将向天文学家使用，以避开观察者数据的离线后处理。我们为DRS提供了初始设计，并定义了天文台和仪器软件系统之间的接口。
Liger is a second generation near-infrared imager and integral field spectrograph (IFS) for the W. M. Keck Observatory that will utilize the capabilities of the Keck All-sky Precision Adaptive-optics (KAPA) system. Liger operates at a wavelength range of 0.81 μm - 2.45 μm and utilizes a slicer and a lenslet array IFS with varying spatial plate scales and fields of view resulting in hundreds of modes available to the astronomer. Because of the high level of complexity in the raw data formats for the slicer and lenslet IFS modes, Liger must be designed in conjunction with a Data Reduction System (DRS) which will reduce data from the instrument in real-time and deliver science-ready data products to the observer. The DRS will reduce raw imager and IFS frames from the readout system and provide 2D and 3D data products via custom quick-look visualization tools suited to the presentation of IFS data. The DRS will provide the reduced data to the Keck Observatory Archive (KOA) and will be available to astronomers for offline post-processing of observer data. We present an initial design for the DRS and define the interfaces between observatory and instrument software systems.
