When I edit my station, I can set “Minimum horizon (Your station minimum observation elevation)”. Let’s say I set it to 45° and save. Now, when I click “Calculate future passes”, I get three observations (max. elevations 89°, 68° and 80°).
If I go back and edit my station to set minimum horizon to 0° and save, and then click “Calculate future passes”, of course I get a lot more. But if I click the filter, and set “Max. elevation” to 45°, I get 63 (!) observations - many higher than 80° elevation.
Why this discrepancy - shouldn’t these two methods yield at least approximately the same results?
