| The IMCCE, named Service des calculs et de mécanique céleste du Bureau des longitudes until 1998, is in charge to build and publish ephemerides. |
| Table 1 lists the stations, their latitudes, longitudes, elevations above sea level and the time periods for which data are studied. |
| Burkina Faso is a West African country located between the 10thand 15th northern parallels and longitudes 2°20' east and 5°30' west. |
| A world known only to her and one in which mice and birds have etched meridians and longitudes, mapping her territory. |
| Latitudes and longitudes were known for each site, but the precise relationship between them was not known. |
| Instead, as is shown on the map, most co-tidal lines lie at a marked angle to the longitudes and some are even perpendicular to them. |
