The five values of B and the corresponding best-fit values of A used to compute the
Mode-5 distributions shown in Figure 9 through Figure 13 are tabulated in Table 20. It
is apparent that the value of A is dependent on both qcx. and B. In general, if a larger
value of B is selected, a larger value of A is required to effect a fit with the random-
attitude-tum data. On the other hand, if the breakup qcx. is increased, the required
value of A must be decreased. Only qcx. is critical since, as shown later, any value of B,
together with its corresponding value of A, can be used in the launch-area risk
computations if significant targets do not lie within ±80° of the flight line.
