AstronomyDetermination of time, longitude, latitude, and azimuth . EIGHTY-FOOT WOODEN PIER USED FOR THEODOLITE AND ZENITH TELESCOPE. DETERMINATION OF AZIMUTH. 143 GENERAL FORMULA. Four methods of determining azimuth will be treated in detail in this publication, namely,(1) the method in which a direction theodolite is used, as in the measurement of horizontaldirections; (2) the method of repetitions with a repeating theodolite; (3) the micrometricmethod, using an eyepiece micrometer; (4) the determination of azimuth from time observa-tions with a transit or meridian telescope approxim

The computation of the azimuth of a terrestrial line of sight from a set of azimuth observa-tions consists essentially of a computation of the azimuth of the star at the instant of observa-tion, a computation of the horizontal angle between the star and the mark, and the combinationof these two results by addition or subtraction.
