History

Which positional error arises when an astrolabe's alidade pins become bent?

A)Inaccurate solar altitude measurements
B)Incorrect sidereal time calculation
C)Elliptical star position readings
D)Reversed zodiac constellation order

💡 Explanation

Bent alidade pins induce parallax error because angular measurements rely on precise alignment between aiming points and scale markings; therefore solar altitude will be incorrect, rather than influencing time, causing elliptical distortion, or altering constellation arrangements.
