20000725: brightness legend on satellite pictures

Chris,

I have one more routine for you to try out.
In the ~gbuddy/nawips-5.4/patches directory is a copy of 
$GARPHOME/gempak/pointerinfo.c.
You can move your current copy from pointerinfo.c to pointerinfo.c.old,
then download the new version to pointerinfo.c.

Finally, make and install Garp with:
cd $GARPHOME
make all
make install


this will enable the pointer within the image area to return the value
interpolated back from the Raw pixel value.

One thing to note- all of these products are multi-part calibrartions.
Eg, for PW products, pixel values 0 through 200 represent PW values from
0 to 67mm. Pixel values 201-255 represent cloud top temperatures -
and not PW values. So, the values displayed for the pointer return
PW values only where those pixels exist and represent PW.

Feedback is appreciated!
