Hi Eric,

No worries.

The best way to do this is to use the LDM 'notifyme' utility to list out
the products from the datastream desired. For instance, try the following:
<as 'ldm'>
notifyme -vxl- -f NIMAGE -o 3600 -h idd.cise-nsf.gov
The listing will look something like:

The product IDs for the NIMAGE datastream are pretty clear:
GOES-12 -> GOES-East
VIS -> visible image ( 0.65 um)
3.9 -> short wave IR ( 3.9 um)
WV -> water vapor ( 6.[58] um) (depends on GOES-East vs GOES-West
Ir -> thermal IR (10.7 um)
13.3 -> long wave IR (13.3 um)
etc.
One ~ldm/etc/ldmd.conf request for GOES-East VIS images only would look like:
request NIMAGE "GOES-12/VIS" upstream.feed.host
There are others that would also work depending on which products you want.
Use the '-p' (pattern) flag on 'notifyme' to test your patterns:
notifyme -vxl- -f NIMAGE -o 3600 -h idd.cise-nsf.gov -p 'GOES-12/VIS'
Refine the pattern value to get just the set of images you want and then
use that pattern in the ~ldm/etc/ldmd.conf request line. After making
the addition/change to ldmd.conf, you will need to stop and restart your
LDM for the change to take effect.

OK. You should be aware that GEMPAK has a script that can be run to generate
ldmd.conf and pqact.conf entries. Please review the GEMPAK HomePage for
