Imaging Data from Sub-Seasonal Variation in Neptune's Mid-Infrared Emission by Roman et al.

Images of Neptune as used in Imaging Data from Sub-Seasonal Variation in Neptune's Mid-Infrared Emission by Michael T. Roman, Leigh N. Fletcher, Glenn S. Orton, Thomas K. Greathouse, Julianne I. Moses, Naomi Rowe-Gurney, Patrick G. J. Irwin, Arrate Antunano, James Sinclair, Yasumasa Kasaba, Takuya Fujiyoshi, Imke de Pater, Heidi B. Hammel. Data are from various observatories/telescope instruments, including: The European Southern Observatory's Very Large Telescope, VISIR Keck Observatory, LWS Subaru Observatory, COMICS Gemini North, Michelle and TEXES Gemini South, T-ReCS Data were acquired from observatory archives and flux calibrated, when possible, by comparison to standard stars, with spectral radiances expressed in units of W/m2/sr/micron. North is up in the images. The first extension (ext=0) is the image in native spatial resolution. The second extension (ext=1) features the disk normalized in size to that of the finest data (i.e., to a disk with an equatorial width of 51.8 pixels, as imaged by VLT-VISIR on August 13, 2018). Image file names and times correspond to approximate mid-time of combined image sequences, and will differ from original file headers. Questions concerning these data should be directed towards Michael Roman, [e-mail] or [e-mail]本数据集为Michael T. Roman、Leigh N. Fletcher、Glenn S. Orton、Thomas K. Greathouse、Julianne I. Moses、Naomi Rowe-Gurney、Patrick G. J. Irwin、Arrate Antunano、James Sinclair、Yasumasa Kasaba、Takuya Fujiyoshi、Imke de Pater、Heidi B. Hammel所著《海王星中红外辐射次季节变化的成像数据》中所用的海王星影像。 本数据集数据源自多座天文台及望远镜设备，具体包括： 欧洲南方天文台（European Southern Observatory）甚大望远镜（Very Large Telescope）的VISIR仪器 凯克天文台（Keck Observatory）的LWS仪器 昴星团天文台（Subaru Observatory）的COMICS仪器 北双子座望远镜（Gemini North）的Michelle与TEXES仪器 南双子座望远镜（Gemini South）的T-ReCS仪器 本数据集数据均来自天文台档案库，且在可行情况下通过与标准星比对完成流量定标；光谱辐射亮度的单位为W/m²/sr/μm。影像均采用北向上的坐标系。文件的第一个扩展片段（ext=0）为原始空间分辨率的海王星影像；第二个扩展片段（ext=1）则是将海王星盘面尺寸归一化至最高分辨率数据对应的盘面大小，即等效于2018年8月13日VLT-VISIR拍摄的、赤道宽度为51.8像素的海王星盘面。 影像文件名与对应时间为合并影像序列的近似中点时刻，与原始文件头中的时间信息存在差异。 若对本数据集有任何疑问，请联系Michael Roman，邮箱：[e-mail] 或 [e-mail]
