Notes. Units: amplitudes in μas, periods in mean solar days. The IERS fundamental nutation arguments l, l′, F, D, Ω, LMe, LSa, LU, and LNe have 0 coefficients and are not shown. Effect origin code: 0 indirect Moon; 1 indirect Sun; 2 direct Venus; 5 direct Jupiter. Δψ & Δε are displayed as integers as in the original MHB2000 routine.
