... The Australia Telescope is the premier imaging radio interferometer in the Southern hemisphere, and the only such modern instrument positioned able to observe SN 1987A. The compact array consists of six 22m antennas with a maximum baseline length of six kilometers. Additional Australian antennas can be combined with the Australia Telescope Compact Array (ATCA) for Very Long Baseline observations, but to date there are no detections of the supernova on baselines longer than six km. ...

From Keith Arnaud: The reactions I recall to my comments about saving posterior distributions were that Jeff Scargle was very sceptical about using other peoples posterior distributions as priors since it would lead to errors propagating. He preferred neutral priors. ... If you took posteriors on two parameters from different experiments and combined them as a prior and the two experiments themselves used the same prior then you would include this prior twice. ...
