... In this paper, results are presented on studies which have been performed to investigate the impact of the cut-off elevation angle and elevation-dependent weighting on the EOP estimates and baseline length repeatability. ... He tested his method with the actual CONT05 observations. ... This gave an impulse to the present work where some results are presented of investigation of the impact of the CEA and EDW on the baseline length repeatability (BLR) and Earth rotation parameters (EOP) estimates. ...

... After all we cannot send a probe to the star Altair to confirm that it is 17 light years away. ... The "Bessel determined that the star 61 Cygni was about ten light years away" Earth goes around the Sun in one year, so in six month it is in the opposite position in its orbit. ... In 1838 Bessel determined that the star 61 Cygni had a parallax of 0.314 arcseconds and therefore the star was about ten light years away (today the distance is more precisely measured to be 11.4 light years). ...
