Parameter: Converts omnidirectional fluxes to unidirectional fluxes or vice versa

Brief Description:
The Flux Omni Uni Transformations (FLOUT) program integrates over a set of unidirectional flux data to obtain omnidirectional flux, or, alternatively, differentiates omnidirectional flux data to obtain unidirectional flux. The input data is an array of flux values (either omni- or unidirectional) as a function of either magnetic field strength or the cosine of the equatorial pitch angle. A complete set of points is required spanning the region along the field line from the point of interest to the atmospheric cutoff.
