Time series of the effect of Galactic aberration on the CIP location (top plot) and ERA (bottom plot) in ± 500 years around J2000.0, based on the ICRF1 and ICRF2 defining source positions. The CIP location X and Y, necessary for computing ΔX, ΔY, and Δ(ERA − s) are derived from the IAU 2006/2000 precession-nutation model.
