The basic rule is always going to be... don't expect reliable results when you are looking at things close to the resolution of the data. For images, we can't interpret reliably if we have fewer than 4 or 5 pixels across the object of interest - and even more would be better. Stereo DEMs are even more removed from the raw data (the images), so their effective resolution is lower still. Their resolution will be determined by the spacing between common points, the identifiable points matched in the two images so parallax can be measured. If you look at the images you can get a sense of how far apart those points would be.
So please don't read too much into tiny details in images or DEMs. Phil -------------------- ... because the Solar System ain't gonna map itself.
