Could it be that histo-matching works nicely only on 0-255 ranges but doesn't 
play nice in ranges 0-1.0? Integers only?

For example, when feeding images ranging from 0-1.0 (all Landsat bands 3) with 
the optional parameter "max=1", many of the histo-matched images are "flatten" 
to 1.

I will try to "recode" 0-1.0 images to 0-255 and repeat the histo-matching 
process.

Best, Nikos
