The 1919 eclipse observations were not very good, in terms of accuracy and constraining GR (or its competitors).mhernan said:mhernan replies.
No I mentionmed th e1919 eclipse studies that launched Einstein and jammed the relativity theory down our mental gullets. It's propaganda.
However, radio VBLI observations have improved the accuracy of this particular test considerably, to ~1 part in 10,000. Further, the deflection has now been measured far from the Sun, and GR passed those tests. Further2, it's not just radio, http://astro.estec.esa.nl/Hipparcos/ [Broken] increased the accuracy of tests in the visible light part of the spectrum.
Details of these tests, and much much more, can be found http://relativity.livingreviews.org/Articles/lrr-2001-4/ [Broken]
