Notes:
For understanding DIs and how they are calculated, please read this article!
(*): Distance, magnitudes and PAs are from Burnham's Celestial Handbook, so updated values can show some differences. Due to this, DI (Difficulty Index) are given for Burnham's data.
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. For an explanation about how to interpret and use DIs, click on the DI link in the respective column above.
(1): Actually, separation between components of 44 Bootes is greater than 1.0" (1.8", 1992)
