    Andres,

    Nice graph of sight reduction methods.

    I do have a question.  You put Lunar method under Longitude.  I thought a lunar was used only to get a crude GMT ( GAT ) and that that time hack could be used as if from a clock.  Historicaly the lunar method was used before the Sumner line so was used with a time sight to get longitude but can the lunar time hack be used like any other time hack with the St. Hilaire and HO 249?

    Thanks.  John H.
