It is perhape as reasonable to attribute the differences as much to error in the MOTS range xs to error in the travel-time ranges, but, since this cannot be proved, the given root-mean-square difference of 3.6 per cent is taken as the best empirical ostimate of the standard deviation of the Table A.2— AVERAGE SHOCK VELOCITY, KING SHOT Cantater No. aP/P, v/é G, ft/sec VV, ft/sec 2 3 5 6 7 9 10 11 0.230 0.152 0,157 0.0374 0.0764 0.0781 0.0773 0.0735 1,524 1.388 1.95 1, 2F 1.224 1,228 1.226 4,217 1126 1119 1115 1110 1130 1125 1126 1123 1716 1548 1555 1252 1383 1382 1380 1367 Wp, ft/sec V+ We ~28 -29 —26 -34 -34 ~34 -34 ~34 1688 1519 1529 1218 1349 1348 1346 1333 travel-time ranges. In any case the percentage error in range is probably smaller than the percentage error in the measurement of peak overpressure. “ REFERENCE 1. J. W.
