Jordan, thanks for passing this along to me.  I've made the change for 6.6.0 to

> Hello Scott,

> I discovered a bug in the Unidata version of N-AWIPS 6.4.0:

> This leads to incorrect mapping of certain GINI files on the Alaska
> National domain (images are placed too far south and east).  If this is
> in your code, we will need it to be changed prior to using the AVHRR
> imagery in N-AWIPS.  Modifications to that same file would also be
> required so that for values of isat = 24 to 29, imsorc = 41.
