[IDV #MOH-422117]: IDV - Location of grib.jar file

If you get the right parameters it's using your table. ;-)

The entries in grib1lookuptable.lst specify the originating center
and subcenter.  A dump on your grib file indicates that  the center
is 7 (NCEP) and the subcenter is 5 (HPC).

Changing your table from:

57:       1:               2:    grib_thesis.tab

to 

7:       5:               2:    grib_thesis.tab

make this work.

Since you are putting your files in your local .metapps/DefaultIdv
directory, you don't need to set up the sitepath since that's
already scanned as the user path.  The sitepath would only be necessary
if you wanted to access this table from multiple systems. In that
case, you would put the files on a shared location and then point
your sitepath there.
 
> For reference I attached the files I created. Not sure if it will help.

That helped, thanks.
