A COMPUTER METHOD FOR THE AUTOMATIC REDUCTION OF SPECTROSCOPIC DATA,
Abstract
A computer program, for use with an associated spectral comparator, was developed for automatically reducing spectroscopic data. A digitizing magnetic-tape recorder, in conjunction with a microphotometer, allows wavelength and intensity information to be read from a photographic plate at 25 data pairs per second. A computer program written Fortran IV was designed to facilitate processing the information into a usable form. The computer program permits analysis of spectroscopic data by making simple specifications on a control card. Useful features of the program are its capabilities of (a) recognizing spectral peaks from a background of variable density and (b) obtaining absolute values for the radiance or irradiance. The program's essential characteristic is the significant amount of time saved in reducing photographic spectroscopic data. As a rough estimate of the time-saving advantage, one may obtain thirty times the information in 1/100 of the time, as compared to manual reduction of spectroscopic data. (Author)
