Fig. 2
Logarithmically scaled Chandra image of the innermost 
of M 31 which combines all HRC-I observations analysed in this work (see Table 1). The images were not binned (HRC electronic pixel size = 
) but were smoothed with a Gaussian of FWHM 
. The X-ray counterparts of novae in the field, which are not all visible in this image, are marked with black circles.
