20131004 Search for Smallest Scan

Now with updated dual analysis and proper analysis of the horizontal size it is much better to look through the data again from February to March to see what the smallest scan size is. Note, must have a horizontal and vertical scan under the same conditions.

Nothing better in this shift. There is a quad scan, but the machine broke in the middle. If time, may be nice to look at.

This is small, but the fit's not wonderful - ie the wings aren't great. This is probably because of scan variation (higher charge) at that point, but mostly due to laser information not quite matching

This is the one.
