in obtaining compass errors by observing compass bearings of celestial bodies at low altitude,the errors in calculating celestial body's bearings will have a direct influence on the accuracy of the observed compass errors.By compiling a computer program with computer-human dialogues and further by displaying a variation curve of errors in calculating celestial body's bearings,the variation of the errors in calculating celestial body's bearings will be readily understood,so that the best timing of observation can be selected to further improve the accuracy in calculation the above bearings.
