This version introduces extra parameters to describe the year-periodic motion of the stations: {{mvar|A}} (generallyamplitude) attributedand to{{mvar|φ}} (phase) per-axis. This sort of seasonal variation; has an amplitude of around 1&nbsp;cm and is attributed to non-tidal loading effects (e.g. the shifting weight of water).
