> Description of problem: I'm unable to get IDV to recognize NCDF trajectory 
> files that I'm creating.  I've verified that IDV recognizes a "track.nc" file 
> available in one of the workshop packages but neither my own single 
> trajectory file nor my own multiple trajectory file (this is what I really 
> need to visualize) can be read.  To the best of my knowledge I'm adhering to 
> the CF Version 1.6 conventions (I've tested them in an online compliance 
> checker).  I've included both headers below.
