초록
In order to computerize the sight reduction process completely, the coordinates of celestial bodies have to be calculated. The author calculates the equtorial coordinates of the sun and stars using formulae by computer programming. And they are compared with data from an nautical almanac. Generally, data based on formulae is slightly less accurate than those derived from an nautical almanac. In the case of calculating coordinates of the sun, maximum error of GHA is 0'.2, and that of declination is 0'.1.
