We only wanted to do 2D tracking with the vertical angle preset so the cell would be pointed at the sun at time of peak altitude. This created a problem that small pitches in the platform would though off the data and it would be hard to tell in the data if we had a low performance in the cell or the tracker was just playing chase from the pitching. We could have really worked with the data afterwords, but I hate noisy data. By scanning the sun we can see in the data exactly when we're pointing at the sun (we took data five times a second). We could extract just those point and start with a much cleaner data set. I would have to dig out the numbers to get percentage of performance increase. I remember it was pretty impressive.
