time forthe first few hundred feet (about 500 feet in this case), and
then for several hundred feet, the increase in shock velocity accompanying Mach stem formation mst be considered; for the remainder of the
path, the reflection factor is used,
When the path length is great, there
is no advantage in using this involved procedure, owing to the uncertainty
about the reflection factor.
Yields obtained using reflection factors
of 2 and of 1.6 over the entire path length are given in Table 10.2-l.
