Notes:
For understanding DIs and how they are calculated, please read this article!
Difficulty Indexes written in red are experimental in this program because it's the first time we are using them on faint stars, so this observing set of doubles have an added goal: To adjust and perfectionate the evaluation system..
n/a: Not aplicable because the Fuzzy-logic based prototype to evaluate difficulty in splitting double stars is bounded between 1.0" and 10.0" seconds of arc
