The late absorptive effects of Shot 4 observed at Site Elmer
(Fige 3.2, 03715 to 1600 hours) were found also in the data taken
there following Shots 1, 2, and 5, but not 3, as show in Table 3.1.
This table and the corresponding Table 3.2 for Rongerik were compiled
from a thorough examination of the scaled data.
Although there was;
of necessity, a certain amount of subjective interpretation (due to
definition of "normal" and to some erraticism of absorption), Tables
3a and 3.2 present a fairly accurate overall picture.
There appears
to have been striking similarity, for all four very large shots, in the
ending time of complete absorption at Rongerik and of the renewed absorption at Elmer, as well as in the time of return to normal minimum
frequencies at each location.
