With the help of Pete, I finally have identified the problem, but I do not
know how to solve it.
I had NEXRAD NIDS plotting of N0Z for years without problem (station KCXX).
Since it has been removed, I am switching to N0Q.
The plot is done using sfmap and a PSC device.
With the new N0Q in place, with proper entries in imgtyp.tbl as well
as nex2gini.tbl, it works well with the GIF driver, but it doesn not work
properly with the PSC driver, as all echos are the same color. Here is an
example with the same datafile as input, and the only difference here being
the DEVICE driver (GIF vs PSC).
Any hint on why it gives those incorrect results for the PSC driver?
