A User's Manual for the FIT Program: A Model for Smoothing Raw Data.

Abstract

FIT ia a Fortran 77 program which fits a smooth curve to raw data. The program finds the trends inherent in the data (the peaks, valleys, slopes, etc.) and produces a set of modified data points, which can be plotted using any available graphics package. It is easily used without much knowledge of the underlying techniques and can be employed repeatedly to the subsequent smoothed data sets to achieve any smoothness desired. However, some care must be taken, since the input data must be equally spaced in the independent variable with only a few missing data points. This report covers input preparation, output expectation, technique explanation and provides a program listing in the appendix.
