FIND/POSINC infram x_pos,y_pos rin,rout,rstep 
	find the position angle and inclination of a galaxy
\us\pu
Purpose:    Find the position angle and inclination of a galaxy
\up\sy
Syntax:     FIND/POSINC infram x_pos,y_pos rin,rout,rstep 
\ys\pa
            infram = input frame
\ap\pa
            x_pos,y_pos = center of galaxy in x, center of galaxy in y.
\ap\pa
            rin,rout,rstep = inner radius, outer radius, step in radius.
\ap\no
Note:       The program estimtes the position angle and inclination of
            a galaxy using the variation of the 2nd fourier harmonic.
            The coordinate input is assumed to be in pixel units.
            The results are written in the keyword OUTPUTR(1:4). These
            results are: x centre position, y centre position, the position
            angle and the inclination (the last both in degrees).
