    Note, there is an apparent typographical error in the "calcul de l'heure de paris par une distance lunaire" example of Arago. the "formules." for both RA and Dec have the second term shown as sin squared. it seem is should be sin of twice the angle. (see for example Chauvenet)

    My comment : Where exactly were you able to find such "formules" in Arago's Treaty? I cannot locate/identify them.
