COMPUTE/FCOEFF infram orient rin,rout,rstep outtab
	compute fourier coefficients of azimuthal profiles in spiral galaxies
\us\pu
Purpose:    Compute fourier coefficients of azimuthal profiles of spiral 
            galaxies
\up\sy
Syntax:     COMPUTE/FCOEFF infram orient rin,rout,rstep outtab
\ys\pa
            infram = input frame
\ap\pa
            orient = center of galaxy in x, center of galaxy in y,
                     position angle, inclination. 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.
