Hi Rick,

re: what to return for dBZ values
> We should probably go finer.

I will take a look at this in the next couple of days.  I do not,
however, think that this should hold-up the inclusion of support
for the new products in the next fastrack/release.

This is likely not possible given that the "low resolution" images values
are in bins whose widths are set in the image itself and the "high resolution"
images have a one-to-one correspondence between "raw" value and "calibrated"
equivalent. Also, all images set the relationship between "raw" value and its
"calibrated" equivalent. Changing this would be tricky at best and error prone
at worst.

The last thing to note is that the "low resolution" images will be removed
from NOAAPort in the December time frame, so making "low resolution" images
match the "high resolution" ones would only have an impact for a short period
of time.

Cheers,

Tom
