Abstract

Results of a charge coupled device (CCD) sounding rocket observation (36.092UH, 1995 May) of the X-ray background between 0.3 and 10 keV are presented. The target for the 36.092UH flight was a high-latitude region of the X-ray background centered at l = 96°.3, b = +48°.1 toward the constellation Draco. CCD spectra obtained from this observation were fitted independently and simultaneously to a PSPC spectrum obtained from a nearby ROSAT field (RP 70137). Above 1 keV, the high-latitude CCD data are well fitted by a single absorbed 9.5E-1.4 power law. Below 1 keV, CCD and PSPC data are fitted equally well by the addition of a cosmic abundance thermal plasma (kT = 0.14 keV) or by a thermal bremstrahhlung component plus an O VII line at 0.574 keV.
