We generated spatial power spectrum densities (PSD) of blank X-ray skies observed with Suzaku X-ray observatory utilizing the modified $\\Delta$-variance method. Using the total measured count rate as the diagnostic tool, we found that a model consisting of the sum of two components, one for the unresolved faint point sources and one for the uniform flat-field emission, can well represent the observed PSD in three different energy bands (0.2-","authors_text":"Kazuhisa Mitsuda, Noriko Y.
