Hello,
I would like to get an information about the use of "intercept method" (or St Hilaire method) in USA.
It seems to me that this method had been used in France before 1900 (it is logical, because St Hilaire was french !). But when this method is become usual in USA ?
The reason of my question is the fact that the HO 203 tables was published in 1923, and these tables was use only for the calculation of hour angle and azimuth ... for Sumner's method ! But I know that tables as HO 208 or HO 211 was already used for intercept method.
Thank you in advance.
Best Regards
Jacques
