   - The alignment shift parameters will be applied to the input data.
   - **IMPORTANT**: Input aligned images will be resized such that the original user-provided radius will be now target_radius and the box size target_nx + xr - 1.  The pixel size of the modified data is thus original_pixel_size * original_radius_size / target_radius.
-    * The pseudo-code for adjusting the size of the radius and the size of the images is as follows:

     * The target_radius and target_nx options allow the user to finely adjust the image so that it contains enough background information.
   - The program will iterate through generations of ISAC2 by alternating two steps. The outcome of these two steps is in subdirectory generation_*** (stars replaced by the current generation number).
