-For more information on this procedure as implmented in MPoL, see the {class}`~mpol.gridding.Gridder` class and the source code of its {func}`~mpol.gridding.Gridder.get_dirty_image` method. When the grid of ${\cal V}_{u,v}$ values is not fully sampled (as in any real-world interferometric observation), there are many subtleties beyond this simple equation that warrant consideration when synthesizing an image via inverse Fourier transform. For more information, consult the seminal [Ph.D. thesis](http://www.aoc.nrao.edu/dissertations/dbriggs/) of Daniel Briggs.
