bombing errors

1. 50 percent Circular Error--The radius of a circle, with the center at a desired mean point of impact, which contains half the missiles independently aimed to hit the desired mean point of impact.
2. 50 percent Deflection Error--Half the distance between two lines, drawn parallel to the aircraft's track and equidistant from the desired mean point of impact, which contains half the missiles independently aimed to hit the desired mean point of impact.
3. 50 percent Range Error--Half the distance between two lines drawn perpendicular to the aircraft's track equidistant from the desired mean point of impact, which contains half the missiles independently aimed to hit the desired mean point of impact. (Note: Above errors should imply overall errors unless otherwise stipulated by inclusion of the word "Random" or "Systematic" as necessary.)
