Table 1: Angular rates of rotation and internal errors obtained from the comparison of FK5 and Hipparcos proper motions for different sets of stars (d stands for stellar distance).
Table 2: Angular rates of rotation estimated for 4 different sets of HCRF proper motions referred to the ICRF. X, Y, Z denote the components of solar motion in equatorial coordinates, "P'' is Oort's constant related to differential galactic rotation, "d'' stands for stellar distance, "elim'' for elimination of residuals and "no'' refers to the number of HCRF stars.
Table 3: Surplus angular rates of rotation produced by the subset of Hipparcos proper motions of Case 3 based on the standard value of the Oort constant, Q=-2.53 mas/yr, and its variations for comparison (errors are only given for the standard value of Q as those of the comparative cases are almost identical).
Table 4: Rotational offsets of Hipparcos and FK5 proper motions required to constrain the comparison of the two proper motion systems to the VLBI-determined correction of the luni-solar precession, $\Delta p=-3.0$ mas/yr.
