Description/Abstract:
THE PURPOSE OF THIS REPORT IS TO PRESENT A COMPLETE ANALYSIS OF THE WO RK DONE TO DATE ON THE POST-DETONATION PHENOMENA FROM THE SANDSTONE FI LMS. DUE TO THE EXTREME CHANGES IN BRIGHTNESS AFTER DETONATION, A LARG E NUMBER OF FRAMES FROM EACH FILM HAD IMPROPER EXPOSURES. THE FASTAX F ILMS WERE MOST USEFUL DURING THE FIRST THIRTY MILLISECONDS SINCE THE S HORTER EXPOSURE TIME LIMITED THE DYNAMIC ERROR AND TIME COULD BE MEASU RED ACCURATELY FROM THE TIME MARKERS ON THE FILM. THE MITCHELL FILMS G AVE GOOD RESOLUTION AFTER THIRY MILLISECONDS, BUT THE ABSENCE OF TIME MARKERS MADE TIME MEASUREMENTS UNCERTAIN. THE LACK OF A VALUE FOR THE CAMERA-TO-AIRCRAFT DISTANCE OR ACCURATE POSITION MARKERS ON THE WATER SURFACE LIMIT THE MEASUREMENT TO ACCURACIES OF LESS THAN PLUS OR MINUS 100 METERS ON THE BEST OF THE AERIAL PHOTOGRAPHS. A NUMBER OF REPORTS BY THE J-7 PHOTOGRAPHIC ANALYSIS SUB-GROUP HAVE BEEN INCORPORATED INT O THIS ACCOUNT. THE REPORTS USED ARE: LAMS-921 - ANALYSIS OF FIREBALL GROWTH AT SANDSTONE, LAB-J-7 - ANALYSIS OF SPIKE GROWTH AND FIREBALL H EIGHT AT SANDSTONE, LAB-J-705 - MACH STEM HEIGHT VERSUS HORIZONTAL DIS TANCE DETERMINATIONS, AND LAB-J-786 - EVALUATIONS OF THE ERRORS IN THE LAMS-921 SPACE-TIME CURVE.
