Harry,

I found the problem with the temperature readout.

In $GARPHOME/gempak/pointerinfo.c, the call to im_btot to convert from the
raw pixel value to the temperature now requires an integer instead of a
real value due to a 1999 change to im_btot at NCEP.

Change:
pointerinfo.c:      temp = im_btot ( &fdvalue );
to
pointerinfo.c:      temp = im_btot(&dvalue);

Then recompile and install garp:
cd $GARPHOME
make clean
make all
make install
make clean
