ASCA SIS0 Image of NGC 253
This image shows an X-ray image of NGC 253
in the 2.0-10 keV bandpass obtained with the ASCA SIS0.
The positions of the point sources and nucleus discussed in
Fabbiano & Trincieri 1984, ApJ, 286, 491 are shown as well as the NED
position of SN1940E. Also shown (RX-1) is a new source visible in later ROSAT
images. The point sources are clearly more prominent above 2 keV compared with
the 0.5-2.0 keV image.
The scale of this image is 10' by 10' corresponding to 7.3 kpc by 7.3 kpc
assuming a distance of 2.5 Mpc to NGC 253.
