摘要

The Spectrograph for Photometric Imaging with Numeric Reconstruction sounding rocket experiment was launched on 2000 August 4 to record far-ultraviolet (912-1450 ?) spectral and spatial information for the giant reflection nebula in the Upper Scorpius region. The data were divided into three arbitrary bandpasses (912-1029 ?, 1030-1200 ?, and 1235-1450 ?) for which stellar and nebular flux levels were derived. These flux measurements were used to constrain a radiative transfer model and to determine the dust albedo for the Upper Scorpius region. The resulting albedos were 0.28 ± 0.07 for the 912-1029 ? bandpass, 0.33 ± 0.07 for the 1030-1200 ? bandpass, and 0.77 ± 0.13 for the 1235-1450 ? bandpass.
