You are correct that we do not have the tables in the IDV for the
FNMOC grids at sub-center 42.  We are working on generating tables
for that.

You can access a sample GRIB file that does work from NCEP:

http://nomad2.ncep.noaa.gov/pub/gfs/gfs20050829/

(not the .inv files).

We will be documenting the method of adding your own tables
in the next release.
