Hi again Rick,

re:

I just displayed the 20:53:47 image from AMX (Miami) since it has
some strong echos (brightnesses > 160).  I then IMGCOPYed the same
image to a local dataset, and loaded it in another frame.  When
either image is interrogated at the same spot the return value
for RAW and BRIT are the same.  The values that seem to get set
to zero on the local image are ECHO and VIP.

Question:

- is the ECHO and/or VIP values what you are referring to above?

Cheers,

Tom
