DELIN and DELOG codes for graphic representation of gamma ray spectra

Two FORTRAN 4 Codes were developed for graphic representation of the gamma-ray spectra obtained with GeLi detectors and multichannel analyzers. The graphic plotting is carried out with the graphic plotter Mod HP-7221 A, using the graphic package software GRAPHICS-1000. The codes have a great versatility and the representation of gamma spectra can be done in a lineal, semilog, or log-log scale, as desired. The gamma ray spectra data are fed into the computer through magnetic tape or perforated paper tape. The different output options and complementary data are given in a conversational way through a terminal with T.V. display. Among the options that can be selected by the user are the following: smoothing the spectra, drawing the spectra point by point or continuously, and output drawing in 1, 2, or 1 sheets with automatic division of the energy scale.
