Fig. 3. The inner 4´ of the pointed HRI observation. The labeled sources (A-F) are the ones spatially coinciding with the optical disk of NGC 4303 (see text and Table 4 for details). The image is centered on the coordinates of the pointed observation. The distances on the axes are relative to the central X-ray source with the coordinates [FORMULA](2000) = [FORMULA]; [FORMULA](2000) = [FORMULA]. North is up, east is to the left.
