Abstract (from CDS):
The SPEAR (or ``FIMS'') instrumentation has been used to conduct the first large-scale spectral mapping of diffuse cosmic far-ultraviolet (FUV; 900-1750 Å) emission, including important diagnostics of interstellar hot (104-106 K) and photoionized plasmas, H2, and dust-scattered starlight. The instrumentation's performance has allowed for the unprecedented detection of astrophysical diffuse FUV emission lines. A spectral resolution of λ/Δλ∼550 and an imaging resolution of 5' is achieved on-orbit in the Short (900-1150 Å) and Long (1350-1750 Å) bandpass channels within their respective 4°.0x4'.6 and 7°.4x4'.3 fields of view. We describe the SPEAR imaging spectrographs, their performance, and the nature and handling of their data.
