Hi Greg-

Can you send along the errors?  I just tried it using the same version
of Java/Java 3D that is in the installer and didn't have problems.  Are
you running the installer or through WebStart?

Thanks for finding this.  We'll have a look.

Okay. We will fix this.  The name for the radial velocity changed from
Radial Velocity to Velocity For a quick fix, load in a velocity sweep and
change it to the one you want.  Also, set the default range you want.  Then,
from the display control's File->Save menu, choose "Save as Parameter Default"
and the IDV will use those values in the future.

Was this working in 1.3B2?  I've had mixed results trying to probe the
Level II data.

Just the radial products, not things like VAD or raster displays. This
has not been fully tested, so if you want to tr

Good news. ;-)

The times is a problem.  

The old IDV code and the NCDC viewer use the same
code for determining the level (elevation of first radial at a sweep).  The
new code uses the average elevation angle for the entire sweep, thus the
difference.  Which do you think is better to use?

Thanks for taking the time to look at this.
