  ''x<sub>L</sub>    x<sub>R</sub>''                
  ''y<sub>L</sub>    y<sub>R</sub>''

<font size=3>
The function defines the simulated space. ''x<sub>L</sub> ''/'' y<sub>L</sub> ''/'' z<sub>L</sub>'' is the position of the first point in x / y / z-axis, and ''x<sub>R</sub> ''/'' y<sub>R</sub> ''/'' z<sub>R</sub>'' is the position of the last point in x / y / z-axis.<br>
The unit is meter (m).

 $SpaceRegion 
  0.0    200e-6    
  0.0    200e-6
  0.0    200e-6

This means the program simulates the region from (0, 0, 0) to (200, 200, 200) (μm).
