Hyperspectral Cubes From Mosaicked STIS Observations of Uranus ("URANUS-STIS")

Uranus-STIS is a collection of hyperspectral cubes of Uranus, constructed from HST/STIS observations which were obtained in 2002, 2012, and 2015. These data cover half the extent of Uranus with a spatial sampling of 0.0277 arcsec/pixel, and a spectral coverage from 300.4—1020.0 nm with a sampling of 0.4 nm/pixel. The data provided in this collection were obtained with the STIS 0.10" long-slit, which was aligned with the planet's polar axis and stepped across the disk at intervals of 0.152" from center to edge. This observing pattern was executed for both the G430L and G750L gratings. The data were pipeline processed, extracted, calibrated, and combined (see Sromovsky et al. 2018 and references therein), with the uniform spatial and spectral sampling noted above.

Uranus-STIS是一组天王星的高光谱立方体（hyperspectral cubes），由2002年、2012年和2015年获取的HST/STIS观测数据构建而成。这些数据覆盖天王星一半的区域，空间采样率为0.0277角秒/像素（arcsec/pixel），光谱覆盖范围为300.4至1020.0纳米，光谱采样率为0.4纳米/像素。本数据集提供的数据通过STIS的0.10角秒长缝采集，该长缝与行星极轴对齐，并从中心到边缘以0.152角秒的间隔沿盘面步进。这种观测模式对G430L和G750L光栅均适用。数据经过流水线处理、提取、校准与合并（参见Sromovsky等人2018年的研究及其中引用文献），具有上述统一的空间和光谱采样率。
