Fig. 1

Mosaicked count-rate images (MOS-equivalent counts per second per bin) of the northeastern (upper panel) and southwestern (lower panel) limbs of SN 1006 in the 2−4.5 keV band. The bin size is 4′′, and the image is adaptively smoothed to a signal-to-noise ratio of ten. The regions selected for the spectral analysis of the rim are superimposed. North is up and east to the left.
