The Astronomic Direction Calculator, shown in
Figure, is used to calculate azimuths based on sun shots or star shots. Sun shots are based on solar observations by the hour-angle-method using the multiple foresight procedure. Star shots are based on star observations, usually of Polaris, by the hour-angle-method using the single foresight procedure.
Direct and reverse observations can be created by clicking the Create New Observation Set icon.
Direct and reverse observations can be deleted by clicking the Delete Selected Observation icon.
