CIRAS-CFM Display 
The top half of the CIRAS display shows leaf gas exchange (photosynthesis) measured and calculated 
data.    The  lower  half  of  the  display  refers  to  the  CFM  (i.e.  chlorophyll  fluorescence  measured  and 
calculated data).  They are not superimposed because of the differing time scales of the two processes 
(gas exchange and chlorophyll fluorescence), though it is possible to plot the average fluorescence with 
gas exchange parameters.
