At first i thought this might be a problem from the draglink re installation (since that could affect the za error). but cband hi and sbn did not show the same offset, so this is probably a re installation error. ... On 10sep13 i updated the za constant term ( in the pointing models for sbw, cband) to correct for this error. cband za constant : -86.0 => -78.13 asecs . ...

The Steady State model of the Universe was proposed in 1948 by Bondi and Gold and by Hoyle. ... At the time the Steady State model was proposed, the Big Bang model was in trouble because the value of the Hubble constant was clearly bigger than the inverse of the age of the Universe. ... Thus the Steady State model has flat spatial sections like the critical density Big Bang model. ... The Steady State model has no adjustable parameters to correct for this error, but the Big Bang does. ...
