Hello Dave, I owe you an apology and hope that I did not cause too much trouble asking to show your work. With the help of your data I was able to trace the "inconsistency" back to a transcription error: I repeatedly misread your distance to Vega of 61d 36' 0.8" as 61d 36' 08". This naturally would lead to a discrepancy of 4" to 8" in the position. Now, that we agree that the three "observed" distances ARE consistent, can we agree that the 3rd one is redundant? (Really, this is only a different way of saying the same thing.) Can we therefore further agree that one cannot determine time and position from 3 distances in a refraction free world? Herbert
