RESIDUAL/ROMAFOT in_frame out_frame diff_frame [reg_tab]
This command produces two images to display the work just done. The first one is the assembly of all the fitted elementary images and the second is the difference between the original frame and the reconstruction produced by ROMAFOT. While the reconstructed image is essentially heuristic, the resulting difference could be useful to visualise maxima not detected by the searching programs. These images can then be examined with FIND/ROMAFOT or SELECT/ROMAFOT.
In order to estimate the internal error introduced by the presence of other images (error for crowding), the following simulation is generally used.
