← HistoryWhich error increases when an astrolabe's ecliptic plane is significantly warped during construction?
A)Azimuthal reading inaccuracies at horizon
B)Hour angle miscalculation for local time
C)Declination offset for celestial bodies✓
D)Altitude variation with temperature fluctuations
💡 Explanation
When the ecliptic plane is warped, parallax errors increase because the angular measurements related to declination, the celestial latitude, are distorted from their true values in projection. Therefore declination offset errors increase rather than azimuth, hour angle, or altitude variances which depend upon level mounting and consistent thermal expansion factors.
