difi: Did I Find It?

Evaluate linkage completeness and purity for astronomical surveys.

Given a set of observations with known object associations and a set of predicted linkages, difi determines:

• CIFI (Can I Find It?): Which objects are “findable” based on their observation patterns (enough observations, enough nights, etc.)

• DIFI (Did I Find It?): Which linkages are pure, contaminated, or mixed, and what fraction of findable objects were successfully recovered.
