The center of the galaxy should be given in pixel units. \ap\pa rin,rout,rstep = inner radius, outer radius, step in radius. Input is assumed to be in pixel units. \ap\pa outtab = output table. For each of the radii the resulting coefficients will be stored in this table. \ap\no Note: The program first extracts the azimuthal profiles, given the orientation parameters. The profiles are then fourier transformed and the coefficient are stored in the table. The number of coefficients is 7. i.e. the 6th harmonic is included. \on\exs Examples: \ex COMPUTE/FCOEFF myframe 100,100,32,20 20,60,10 mytab \xe\sxe
