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. For an explanation about how to interpret and use DIs, click on the DI link in the column header above.
