← HistoryWhich outcome results from inaccurate alidade alignment within historical astrolabes?
A)Elevated atmospheric refraction calculations
B)Increased error in angular measurements✓
C)Improved celestial object identification
D)Reduced instrument weight and instability
💡 Explanation
In medieval astrolabes, imprecise alidade alignment causes parallax error, a form of systematic measurement error, because it misrepresents the angle to observed celestial objects. Therefore, angular measurement accuracy is diminished, rather than improved identification or atmospheric calculations, under this construction constraint.
