27. It would be an oversimplification to assert that Daigle et al.'s measurements and procedure exactly reproduced the Taylor microscale. The actual situation is complicated by the slow response time of their instrumentation, which would cause the length scales they measured to be larger than the Taylor microscale.

29. The "actual" spectrum in Fig. 3 is modeled by a three-parameter equation involving the incomplete beta function. This equation allows for more realistic modeling of the energy subrange than the von Karman spectrum, and is described in D. K.
