Computations of the polar coordinates are carried out by the use of time data and of latitude data separately. The results from time data and those from latitude data are proved to have mutual differences in annual term in particular. That is, polar loci obtained from latitude results give almost circular forms, while those from time results give elliptic forms elongated rather seriously on the X-axis.
