System/Planet Facility Stacking
	
			 
             
			
		
		
		
		There are various sorts of facilities that have both a system-wide version and a planet-wide version.  
 
Do these two versions compliment each other and stack, or is a planet-wide facility of the same type (such as the intel "databank") useless when in the same system as a system-wide facility? 
 
Thanks in advance.
