Dear all gempak users,

I had to switch recently from the N0Z NEXRAD products to N0Q.

The plotting is done with sfmap using the RAD keyword.

Here is a comparison with another radar product for the same time (the new
N0Q is on the right-hand side).
There is a problem as all the values seem to be all the same... at least
with the same color.

I tried with several LUTFIL and it is always the same.

The pqact.conf is just:
NEXRAD  ^SDUS[23578]. ....
([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(...)(...)
        FILE    -overwrite      -close
 data/gempak/nexrad/NIDS/\5/\4/\4_(\1:yyyy)(\1:mm)\1_\2\3

Any hint on what could be wrong?

Another question is the LUTFIL. Previously I had this colormap with the N0Z
product:

Is there a way to generate a LUTFIL with the same colormap?

Thanks for your help!
