 mosaic_fitgeom_list: dict (*default={"rshift": 10, "rscale": 10, "general": 6}*)
     The different fit geometries tried in alignment as well as their minimum number of objects (minobj) value which specifies the number of matched sources required for a successful fit. For pipeline products, the fitgeometry value is ignored and defaults to a fit geometry of ``rscale``; the code governing the default values is in *align_utils.perform_fit*. The value for minobj specified here, however, is used for the pipeline products.
