 $ranges
 -0.1 10.0 20.0 15.0
 -0.1 10.0 15.0 0.0

This means that there are two rectangular regions. The first region covers the area which x starts from -0.1 um to 10.0 um and y starts from 15.0 um to 20.0 um. 
The second region covers the area which x starts from -0.1 um to 10.0 um and y starts from 0.0 um to 15.0 um.
