Haha, don't know about that. These were made a long time ago, when I was experimenting with GIMP and expecting the heli to go south to Pilots Pinnacle. Manually aligning HELI_NAVs takes a lot of time, and I don't want to get into OpenCV programming to do it automatically. I think Aurélien Genin has already done it.
Maybe by the time the MSR mission goes to Mars I'll have something better.
