DARED-1--AN IBM-704 PROGRAM FOR REDUCING DATA FROM FOIL IRRADIATION AND FITTING BY LEAST SQUARES TO BESSEL J$sub 0$ OR COSINE FUNCTION
A description is given of a code for the IBM-704 computer which reduces and fits by least squares the measurements of radioactivity of a sequence of foils. Corrections for background, counter deadtime, foil weight, and radioactive decay are applied, and readings outside a specified range are rejected. Errors due to statistical fluctuations are computed and off-center ordinates are calculated. Reduced data are then fitted by least squares to the best value of the arguments of Bessel J/sub o/ or cosine functions. Up to 100 foils in a sequence can be handled, and decay times up to 999 min can be accommodated. An IBM-704 computer having 8192 words of core storage is required. No drums or tapes are needed. Running time for a typical 50 point problem involving data reduction alone is 2 min. With least squares fitting, the same problem would require 4 min. (auth)
