FieldOfViewDetector documentation - noting the lack of body awareness
Could the fact that a FieldOfViewDetector is unaware of a body blocking the field of view be added to the documentation page? (https://www.orekit.org/site-orekit-10.3/apidocs/org/orekit/propagation/events/FieldOfViewDetector.html) It would avoid confusion.
The further addition of the example code from https://forum.orekit.org/t/fov-fov-detector-usage-problems/249/8 would be grand too.
The note could read something like:
A FieldOfViewDetector is unaware of any bodies occluding line-of-sight to the target. To include the central body blocking the field of view a BooleanDetector can be combine the FieldOfViewDetector with an ElevationDetector:
final FieldOfViewDetector fd = new FieldOfViewDetector(topocentric_point, field_of_view);
final ElevationDetector ed = new ElevationDetector(topocentric_frame).withConstantElevation(0.);
final BooleanDetector detector = BooleanDetector.andCombine(ed, BooleanDetector.notCombine(fd)).withMaxCheck(maxCheckingInterval);
