It's just a simple .geo like the others you've seen.
First line is the keyword FILENAME and then the filename of the image
Next line is keyword TIEPOINT followed by the pixel x, pixel y, longitude, and
latitude of the pixel
Final line is another TIEPOINT for the opposite corner in the same format.
Explained a bit in README.MAPS and a bit more extensively in the
online help in Xastir itself.
Note that the tiepoints do not have to be at the corners, but you
get a bit more accuracy if they're as close as possible. Pick two
spots on the map that you know the lat/long of, which are separated
both vertically and horizontally at much as possible.
