By adopting the sidereal 'fixed stars' value for the rotation of the

You are aware, are you not, that astronomers use an inertial reference
frame based on the optical and radio postions of distance quasars, to
prevent just such errors?

And if you aren't aware of that, why haven't you paid attention when I
have told you this at least four times over the past year?
