Megan,

The program that I provided that converts the grid into the gini image
creates
a calibrartion block with decreasing temperatures for increasing pixel
values
which causes a problem in the plotting of the IMCBAR labels (due to
the negative number in the log function to determine the number of
decimals to display in the labels). I have a a fix for this in the
current 5.10.2 distribution files.

The 'K' label appears at the top of the color bar, but no numbers along
its side.  I've tried adjusting the frequency of the labels, making the
text smaller, and the colorbar bigger, in case the numbers had no room to
appear.  But so far I've only gotten the 'K' to appear differently. Is
there a setting in IMBAR needs to be changed?
Also, the color table I'm using to plot the satellite image is ir_upc2.

Thanks,
Megan Gentry
