The coordinates on the Bikini grid for the position of the burst 2 as given by Keith Boyer are: 185,100 ¢ 500 E: 96,200 ¢ 100 Horizontal distances and bearings from Bokobyaadaa(Able) station 1519, were worked out for the endpoints and midpoint with results as listed in G& had previously (PPG 2323) placed the burst at N cid Table 10.1-1. E: Height of burst: 185,450 £ 500 96,300 4 150 4,320 £ 150 Yields were calculated according to phi-fifth scaling procedure for the several distances and bearing corresponding to the midpoint and
