Hi Chris:

The NetcdfFile interface gives access to the raw values. If you open with 

  NetcdfDataset.openDataset();

by default it will apply scale/offset.

The FXY value is in the variable attribute BUFR:TableB_descriptor, eg:

  int Orbit number;
     :missing_value = 16777215; // int
     :BUFR:TableB_descriptor = "0-5-40";
     :BUFR:bitWidth = 24; // int

The values with tables should have been converted to Strings via the enum data 
type. Im not sure why they werent, ill have to look at that.

The code is still a bit green, please let me know what other problems you see.
