As the unofficial peer reviewer in the sci.astro.amateur forum ,the
Wiki article is rejected as inconsistent.and unsatisfactory..

The actual experiment conducted at the South Pole was based on the
correect principles which assumes axial rotation at 4 minutes for each
degree of rotation,15 degrees per hour and 24 hours/360 degrees -

There is not basis for referencing axial rotation as an indepedent
motion off celestial sphere geometry via the return of a star to a
terrestrial meridian .
