Face Left and Face Right Observation in a Theodolite

Index error
- The error eliminated by face left and face right observation in a theodolite is the index error.
- Index error is the error caused by the misalignment of the zero mark of the horizontal and vertical circles of the theodolite.
- By taking face left and face right observations, the index error can be eliminated by averaging out the readings from both faces.

Eccentricity error
- Eccentricity error is the error caused by the misalignment of the optical axis with the axis of rotation in the theodolite.
- Face left and face right observations do not directly eliminate eccentricity error, as it requires additional adjustments and calibrations.

Both
- The correct answer is C) Both, as face left and face right observations help in eliminating the index error and also aid in reducing other instrumental errors.
- By taking readings from both faces and averaging them, the overall accuracy and precision of the theodolite measurements are improved.
In conclusion, face left and face right observations play a crucial role in ensuring the accuracy of measurements taken with a theodolite by helping to eliminate index errors and improve overall instrument performance.
