Solving for Z,
Note that LHA is between 180° and 360° and that Z is positive; therefore, the normalized correction equals 0.
Solving for h,
As shown in figure 15-14, the left edge of the sun (indicated by the symbols in the point column) was pointed both
direct and reverse. That being the case, the correction dH is added to the average horizontal angle as follows:
Solving for the azimuth of line AB (Set 1), you obtain the following:
Now, if you use the same calculation procedures to obtain the azimuth of line AB for Sets 2 and 3, you find the
If you desire a bearing, you know that an azimuth of 91°24´03´´ equates to a bearing of S88°35´57´´E.
