Techniques
1. Very high speed streak cameras were used to record the
history of the light arising near the bomb in the first few microseconds to
give time interval,MMM and very early growth of the fireball.
2. Elaborate experiments were devised to measure DELETED

Results
The results of these experiments are contained in the preliminary shot
reports and in the various technical reports made by the groups involved.
The time interval measurements were in agreement with those made by other
methods.
