→Repetition claim of time and location: How do we measure radial velocities?
::::::I don't understand why you have any issue with this one astronomical object's distance. It isn't remarkable in that manner, many supernova remnants are much farther away. The only assumption I am making is those who are writing the original science, peer reviewed papers are not purposely fudging the data (and managed to trick those who reviewed the papers). However if I suspected that, I can conduct similar tests and see if I can duplicate their findings, or discover errors within them. --[[User:BMcP|BMcP]] 14:38, 20 January 2010 (EST)

:::::::I read the beginning of [http://adsabs.harvard.edu/abs/1973PASP...85..579T] with great interest. Unfortunately, though it says, "The dynamical methods all depend on the fact that we can measure both proper motions, in arc seconds year<sup>-1</sup>, and radial velocities, in km sec<sup>-1</sup>," it doesn't go into detail on how we can do that. The arc seconds/year, of course, can just be observed - but how do we measure the radial velocities? (I think your answer would make a great addition to some astronomy article!) --[[User:EvanW|EvanW]] 14:51, 20 January 2010 (EST)
