Strongest open leads

See leads.md for all of them. These would settle the most: 1. Find VM006's AS17 frame number and check its neighbours and film margins (tests both Max and Loeb). 2. Run the unexposed-margin test that set AS11-40-5938's spot A apart from cosmic-ray specks on the Apollo 12 war.gov frames and VM006 too. 3. Measure the Plaskett U shadows on NAC M1146188575L/R. 4. Run the low-sun versus high-sun fractal comparison, or file a HiWish request. 5. Pull Lunar Orbiter III-84M for the Shard and the Tower, and search the Apollo 14 transcript for Leonard's 'Annabel' (Penetration).
