Notes: 
For understanding DIs and how they are calculated, please read this article!
n/a: Not applicable: Difficulty Indexes are calculated only for those doubles that have separations between 1.0 and 10.0 seconds of arc and shine with a difference of magnitude between 0 and 5.
(*) Note:
Because precession of Equinoxes, Otto Struve 181 in Vulpecula is actually located in Constellation Lyra, and not far from Albireo!!. The Burnham's Celestial Handbook lists it in Vulpecula and since these pages are also a homage to his talent and life, it is also included in this project.
