let....i want to plot contour for surface points (x,y) in magn/arcsec^2.
then How can I made the surface magnitude image.?
& how can i fit the parameters ?

The CONTOUR task in the core system only takes an image for input, as does the NEWCONT task in the STSDAS.GRAPHICS.STPLOT package (STSDAS must be installed separately). If what you have are fluxes at a list of (x,y) positions, then have a look at the SURFIT task in the UTILITIES package as a way of fitting the points with a surface to create an image. Once you have that image, the contours can be drawn using the standard tasks.

Hope this helps,
