How do the guiding rates, 1.0x, 0.5x, 0.25x etc translate to motion of
the mount? What are the units?

1x means 1 times sidereal. Therefore in RA the actual guide rate would be
either zero tracking (star drifts at 1x sidereal westward) or 2x tracking (star
drifts 1x sidereal eastward). In Dec the star moves either N or S at 1x
sidereal. 1x sidereal is 15 arc sec per sec. The other rates are half and 1/4 of
that.
