Re: 20051216: FNEXRAD Composite images are jerky

Paul,

The new motherlode machine is faster than the previous machine.
The Level III data is roughly 5-6 minutes between images at a site-
whereas the composites are being generated about every 3 minutes apart now,
where it had taken about 5-6 minutes previously, so you will see frames where
the radar image portion for a site doesn't change from the previous image.
If I slow down the generation plot, the frames will be more in sync with the
change in LEVELIII images.
