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.
