The coordinates of the pole were derived from both time and latitude observations made at eight observatories from 1962 to 1964. The differences between these results and the ILS results show an annual variation. After removal of this term the standard deviation is about ±0′′.03 for the x- and y-components. Corrections to the adopted longitudes and latitudes are obtained and these agree closely with those obtained by the BIH.

RÉSUMÉ

On a déduit les coordonnées du pole simultanément des observations de temps et de latitude faites par huit observatoires de 1962 ä 1964. La différence entre les résultats obtenus et ceux du SIL montre une Variation annuelle. Après correction pour ce terme, la moyenne quadratique des différences est environ 0 '' 03 pour les coordonnées χ et y. On obtient des corrections aux longitudes et latitudes adoptées qui concordent bien avec celles obtenues par le BIH.
