... The particular variables it is concerned with are tick , which is the number of microseconds added to the system time during a clock interrupt, tickadj , which sets the slew rate and resolution used by the adjtime system call, and dosynctodr , which indicates to the kernels on some machines whether they should internally adjust the system clock to keep it in line with time-of-day clock or not. ... Set the kernel variable tickadj to an internally computed "optimal" value. -t tick . ...

... The distance scales of the objects are matched both by comparing the first derivatives of the angular velocity determined separately from radial velocities and proper motions and by the statistical-parallax method. ... Good agreement between the inferred 0 and our calculations based on space velocities suggests that the Lindblad relation holds throughout the entire sample volume. ...
