Halo Array Coverage

Behold the galactic coverage of the Halo rings in all their devastating magnitude. With each Halo having a coverage of 25,000 light years (approximately 146,965,634,289,180,000 miles), and assuming the edges of the six external rings meet at the center (where the Omega Halo, or Installation 07, is located), the arrays cover a diameter of 100,000 light years. You may notice that there are various stars and parts of the galactic arms that stretch outside of the areas of the Halos. It can be conjectured that the initiation of the Omega Halo's firing sequence might augment the radius of the total Halo Array by as much as 500% by recalling 343 Guilty Spark's claim that, upon the arrays firing, all life within three radii of the galaxy would be killed.
The only confirmed locations on this coverage map are Installations 04 (Alpha Halo), 07 (Omega Halo), and 01 (Beta Halo), due to the idea that Omega Halo is in the center of the galaxy and, in turn, puts Beta Halo across from Alpha Halo. If the observation of the Soell System is correct and its central star is, indeed, Iota Horologii, then Alpha Halo is approximately 56 light years from Sol (Our star), and the two would therefore only be under a pixel apart. In this map, however, Installation 04 is instead represented to be between 1150 and 1250 light years distant.
The locations of other four halo rings are ideas based on observations of the surrounding stars and other celestial bodies of Installation 05. For the reason that Delta Halo seems to be surrounded by relatively dense star formation, I have come to the conclusion that, based on this representation of the galaxy, it is located approximately 62 degrees relative to Sol in the galactic longitude, where the edges of the singular ranges of Alpha and Omega Halo meet, which also has a much denser cluster of stars in comparison to its other possible location (assuming, of course, that the Installations number are in sequence and are relative to the surrounding Halos). The rest of the halo rings are arranged in ascending order clockwise around the conjectured location of Omega Halo, or the Nuclear Bulge.

As you can see, a lot of research went into the making of this map, but there is no way I would have been able to make that map alone. The background image of the Milky Way Galaxy is used from Wikipedia's Milky Way article, and the image itself can be found here. The basic design, inspiration, orientation, and mapping of the Halo Array coverage can be found Halopedia's Milky Way article, and the basis image can be found here.

Enjoy!
