Energy Spectra of the Soft X-ray Diffuse Emission in Fourteen Fields Observed with Suzaku

Understand

The soft diffuse X-ray emission of twelve fields observed with Suzaku are presented together with two additional fields from previous analyses.

• All have galactic longitudes 65 deg < l < 295 deg to avoid contributions from the very bright diffuse source that extends at least 30 deg from the Galactic center.
• The surface brightnesses of the Suzaku nine fields for which apparently uncontaminated ROSAT All Sky Survey (RASS) were available were statistically consistent with the RASS values, with an upper limit for differences of 17 x 10^{-6} c s^{-1} amin^{-2} in R45}-band.
• The Ovii and Oviii intensities are well correlated to each other, and Ovii emission shows an intensity floor at ~2 photons s^{-1} cm^{-2 str^{-1} (LU).
