Note. — In this particular example, T (4'' 2*") was taken from a previous 

 calculation, but it may be obtained with a sufficient degree of approximation, 

 by the method described at p. 129 of Appendices to the Nautical Almanac. 



If the angles from the Sun's vertex are required, the parallactic angles 

 must be computed and applied to the above.
