[GEMPAK #MLE-948410]: GRDHDR ignored

Hi Nathan,

Do I understand that you are interpolating the same grid three times, changing 
the Horizontal Remap type flag on GRDHDR each time? And then comparing the 
interpolated grid values and finding no difference?

The language on the GRDHDR man page ( 
http://www.unidata.ucar.edu/software/gempak/man/parm/grdhdr.html ) suggests 
that this flag only has an effect if you are interpolation from one grid 
projection to another.  If you are interpolation from 1 to 4km on the *same* 
grid projection, it would make sense that the flag is not applied. 

Hope that answers your question.
