[1] These time-varying astronomical quantities may well include things like, for example, the mean longitude or imply anomaly of the system, the node of its orbit relative to a reference plane, the way with the apogee or aphelion of its orbit, or the scale of the key axis of its orbit.
[two] In accordance with that substitute historic utilization, an expression which include "correcting the epochs" would consult with the adjustment, normally by a little total, in the values from the tabulated astronomical portions applicable to a hard and fast conventional date and time of reference (instead of, as may be expected from latest use, to a change from one date and time of reference to a different day and time).

a time period, more time or shorter, extraordinary for events of fantastic subsequent influence; a memorable period; as, the epoch of maritime discovery, or from the Reformation
These time-various astronomical quantities might contain, for instance, the mean longitude or signify anomaly of the physique, the node of its orbit relative to a reference airplane, the path with the apogee or aphelion of its orbit, or the size of the major axis of its orbit.
