These are the features I've seen magic triggering on in the pattern.20090722 images (see MaskFeatures090712 for other examples). For pattern.20090722, there were only a few (<5?) streaks in the same direction as tilty streak, but I couldn't find them in the image (too noisy). Most features that get triggered are from burntool.

An example of a satellite streak (top) and what I previously called a vertical streak (bottom), seen in this image:

more examples of burntool

for lack of a better term, a ufo, which was masked by magic.

multiple stripes (black and white), which got masked by magic.

an example of a star artifact with a nearby burntool
