The lunar node is one of the chart points which may be displayed in any chart or grid. In the "Preferences" dialog, "Calculations" tab it is possible to select the lunar node as either the true node or the mean node.

•True Node - is the real position of the moon's node at any time.

•Mean Node - is the position of the moon's node according to a mathematical formula which ignores many of the minor perturbations in its orbit.

Any chart display or report indicates which type of lunar node has been used during its calculation. The lunar node type is not saved with a chart - it is only applied when a chart is being calculated.
