Data Reduction From Photographs of Blasts

Abstract

The report gives a detailed description of a code for reduction of data from blast photographs. The code furnishes data about the orientation of the camera, computes scale factors of the frames, expresses the refractive distortion of the Sun's image in proper angles and determines the parameters of a function R sub o(f), which gives the radius of the blast bubble as a function of the frame number f (i.e., time). The distortion data are corrected by the code for a constant movement of the camera and can be used for the calculation of the air density within the blast bubble by other codes already in use.
