AstronomyDetermination of time, longitude, latitude, and azimuth . e value of one division of the level and w, e and w, e are the west and east readings of the 1 Various other formula? for computing the azimuth of circumpolar stars have been proposed and used. Each of them requires either the sameor a greater time for the computation than that here given, when the whole computation, including the preparation of the auxiliary tables requiredwith some of them, is taken into account. As uniformity of practice is conducive to rapid computation, it is considered desirable that all shoulduse the formula? given, and therefore no others are here stated. It should be noted that the formula given is accurate and general; that is, itapplies to any of the close circumpolars at any hour angle. 2 sin2 i t - If a mean time chronometer is used, the value I — Ln y, should be Increased by its one hundred and eightieth part. 8 This table was copied from pages C34-037 of Doolittles Practical Astronomy. These tabular values may be found in various other places. No. STRUCTURE FOR ELEVATING SIGNAL LAMP OVERTRIANGULATION STATION USED AS MARK. No. 26.
