Description

Note on approximate_distance = .true. vs. approximate_distance = .false.

approximate_distance = .true.
one close points, distance = 0. Can it really be zero? (un)lucky observation location?

Research direction

The issue concerns the approximate_distance setting and compares .true. and .false. results using screenshots; no source file or test is named. Start by locating the implementation or entry point for approximate_distance and reproduce both cases. Done means determining whether a zero distance is expected and documenting or correcting the inconsistent behavior.
