Interactive analysis of magnetic field data

A pair of programs, entitled BANAL and TANAL, have been created in the UCLA Space Sciences Group for the interactive analysis of magnetic field data. These programs reduce the time from the inception of an idea to its testing, and thereby enhance both the productivity and creativity of the user. They accomplish this through menu-driven procedures for the display and analysis of time series data, including Fourier analysis. Cursor selection of sub-sections of the data for entry into the analysis procedures as well as automatic scaling minimize the required keyboard input from the user.
