Branduardi-Raymont, G. ; Fabricant, D. ; Feigelson, E. ; Gorenstein, P. ; Grindlay, J. ; Soltan, A. ; Zamorani, G. Abstract The results of 0.5-3.0 keV X-ray observations of the central region of the Perseus cluster carried out with the Imaging Proportional Counter and High Resolution Imager aboard the Einstein Observatory are reported. In addition to the very extended thermal cluster emission and a sharply peaked component at NGC 1275 previously known, the high resolution image reveals a point source coincident with the optical nucleus of NGC 1275. The 0.5-3.0 keV luminosity of the compact source is approximately 10 to the 44th ergs/sec. The Imaging Proportional Counter data show the cluster emission to be a factor of 1.2 more elongated east-west than north-south. The centroid of the cluster emissions is found to be offset 1.7 arcmin east of NGC 1275, in the direction away from the prominent line of galaxies that stretch between NGC 1275 and IC 310. The cluster center determined from galaxy counts lies 6.4 arcmin southwest of the X-ray centroid.
