 "finding": "The real pass lays onto the ground to within its fitted offset of 1.0 m along track and 2.6 m across (image against predicted brightness, correlation 0.03); the image covers 100% of the site. Its wave reaches at most about 0.3 m into dry sand and less into rock. The published method, run on this image over three pyramids and three stretches of open plateau, draws its columns wherever the registration wanders: on every patch the power at a pixel follows that pixel's trajectory energy (1.0000 or better). Every patch draws columns; the pyramids, whose surfaces are busier, draw more of the strongest (5 to 9% of their pixels are among the noisiest 5% of all, against 1.6 to 3.6% on open plateau), while their typical pixel wanders as much as open plateau's (medians within 7%). Its mean depth profiles are alike over the three pyramids (0.88 to 0.91), whose surfaces are alike, and a pyramid's differs from open plateau's (0.61 to 0.83) by no more than two stretches of open plateau differ from each other (0.44 to 0.72)."
