Note:
These positions were calculated using SkyGlobe and are accurate
for the Boyne Valley area. They will only be approximate for
other latitudes. Also, azimuths will vary according to elevation
and altitude. 2,800BC was chosen as the date on which to base
these calculations because much of the mound-building in the
Boyne Valley would have been completed at this time.
