[IDV #CQE-207112]: Recognition of Fill / Missing value

Hi Chris:

looking at a random 2D variable:

  short AerosolOpticalThicknessPassedThresholdStd(lat=720, lon=1440);
     :_CoordinateAxes = "lat lon ";
     :_FillValue = -32767s; // short
     :units = "NoUnits";
     :Title = "Standard deviation of the spectral Single  ScatteringAlbedo ss 
of aerosol models that passed the threshold.Scaled by a factor 1000.";
     :UniqueFieldDefinition = "OMI-Specific";
     :ScaleFactor = 0.0010; // double
     :Offset = 0.0; // double
     :missing_value = -32767s; // short

ScaleFactor should be scale_factor
Offset should be add_offset

see http://www.unidata.ucar.edu/software/netcdf/docs/BestPractices.html "packed 
data values"

Im detecting missing values ok in toolsUI 4.0. what version IDV?
