FIMS-SPEAR

All data and documentation from the FIMS-SPEAR mission at MAST. FIMS-SPEAR conducted the first large-area spectral survey of the far-ultraviolet sky. Known in Korea as the "Far-Ultraviolet Imaging Spectrograph" (FIMS) and in the US as "Spectroscopy of Plasma Evolution from Astrophysical Radiation" (SPEAR), FIMS-SPEAR was the primary payload on STSAT-1, Korea's first astronomy satellite. This mission comprised dual imaging spectrographs optimized for measuring diffuse emission, including the S-band (900–1150 A) and the L-band (1350–1710 A). Available data products include hyperspectral imaging covering most of the sky, extracted line emission maps, star spectra, and pointed observations of the Vela supernova remnant.

本数据集包含MAST平台下FIMS-SPEAR任务的全部数据与文档资料。FIMS-SPEAR完成了全球首次大视场远紫外天区光谱巡天。该任务在韩国被称为"远紫外成像光谱仪（Far-Ultraviolet Imaging Spectrograph，FIMS）"，在美国则被称为"天体物理辐射等离子体演化光谱仪（Spectroscopy of Plasma Evolution from Astrophysical Radiation，SPEAR）"；FIMS-SPEAR是韩国首颗天文卫星STSAT-1的核心有效载荷。本次任务搭载两台专为弥散辐射测量优化的成像光谱仪，覆盖S波段（900–1150 埃）与L波段（1350–1710 埃）两个观测波段。可获取的数据产品涵盖覆盖绝大多数天区的高光谱成像数据、提取得到的谱线辐射图、恒星光谱，以及针对船帆座超新星遗迹的定向观测成果。
