Notes on Table 4.3 (Continued)

a-The damage did not extend to the surface and is not comparable with

other rounds; the sides of the original charge hole were damaged up to

average slant distance of 5.6 ft from the center of gravity of the
charge.

b-Crater shape was estimated; the breakthrough volume is not included.

c-Average of eight measurements scaled from the vertical crater sections.
