Fig. 6b: The SRC image (left, see Fig. 6a for footprint within HRSC context) in comparison with the corres onding (magnified 
by a factor of 4) portion of the HRSC swath (right). Why the effective improvement in resolution of the SRC over the HRSC 
image falls behind expectations requires further study.
