The inputs to FARS must be data cubes - i.e images with more than 1 
point on the freq axis - in fact many points are best since it does 
Fourier transforms along the FREQ axis (actually lambda squared).  RSOEC 
failed because it too is designed to work with multi-frequency data and 
cannot function suitably with this input file.
