TRIPP_CENT

       Find centroid of star image with DAOPHOT algorithm CNTRD,
       works either by giving approximate coordinates (x,y) or
       interactively by cursor.

       TRIPP_CENT, image, [ xcen, ycen, X=x, Y=y, $
                 FWHM=fwhm, SILENT=silent, SEARCH=search ]

       IMAGE : 2D image array.

       NONE.

       NONE.

       X      : Approximate x coordinate for source, if not existing,
                use cursor for interactive determination.
       Y      : Approximate y coordinate for source.
       FWHM   : FWHM of star images [pixels], if not given,
                program asks for it.
       SEARCH : If search at x,y fails, use area with rectangle side
                length 2*SEARCH [pixel] around x,y for further trials.
       SILENT : No output of coordinates on screen.

       NONE.

       XCEN : Centroid x coordinate of source by CNTRD.
       YCEN : Centroid y coordinate of source by CNTRD.

       NONE.

       NONE.

       NONE.
