Appendix B

 Two examples from Fujiwara et al [1] are shown below which represent two different candles:


Figure 4 Power spectrum for flame fluctuation of candle A
              (Adapted from [1])


Figure 5 Power spectrum for flame fluctuation of candle B
                          (Adapted from [1])


Figures 4 and 5 have to two important features.  They have a flat region at low frequencies and 1/f at high frequencies.   Note how these figures are similar to figure one.
Figures 4 and 5 have fall off as 1/f^1.4 and 1/f^2.5 at high frequencies respectively (a low pass filter has a slope of 1/f2).
