EHANGMETERS. Four Bhangmeters at the control point operated successfully for time-tominimum data, tee \ Insufficient data exist at the present time to allow a closer determination of Bhangmeter yield in this yield range. Time- of~fall data are not yet available. APPENDIX =f Final Estimate of Burst Position ofMMMM(CHEROKEE): The fireball was seen by the Chieerete phototheodolite, whose alignment was found to be accurate within 2' of arc by surveys taken before and after the shot. The Aomoen phototheodolite did not see the fireball directly, but exposure on the edge indicated it was just out of the field of view. Using the radius of the fireball at breakaway, the azimuth of the optical axis and the field of view of the Aomoen phototheodolite, a minimum distance of GZ from the Chieerete photo- theodolite, was obtained. Radar pictures of the fireball were obtained giving absolute position of GZ with a maximum expected error of 500 feet. This point lies on the Chieerete phototheodolite line 500 feet beyond the minimm distance required by the Acmoer phototheodolite,. The Bokebyaadaa camera line of sight gave an intersection with the Chieere phototheodolite line of sight 200 feet nearer than the radar position. " Ree ~ « ib"
