The following values have been used in calculating the mixture fraction:
Total Mass fraction of Oxygen   atoms in the air stream,  Zo,o = 0.233
Total Mass fraction of Carbon   atoms in the air stream,  Zc,o = 0.0
Total Mass fraction of Hydrogen atoms in the air stream,  Zh,o = 0.0
Total Mass fraction of Oxygen   atoms in the fuel stream, Zo,f = 0.0
Total Mass fraction of Carbon   atoms in the fuel stream, Zc,f = 0.7485
Total Mass fraction of Hydrogen atoms in the fuel stream, Zh,f = 0.2515


NOTE: The data presented for this flame should be used with care as
      the measured CO and CO2 signals are affected by fluorescence 
      interferences from soot precursors as well as other species.
