Summary 0000068: Baseline based error RT1-2
Description Tom Oosterloo has noticed that already since a while, for a 20-Mhz line
observation, the data on baseline RT1-2 (both XX and YY) are
systematically too large by a few %. Checking the calibration etc, Tom
comes to the conclusion that there is a baseline based error on this
baseline. Attached is a plot of data of 3C295 of amplitude vs uvdistance
to illustrate. You can spot the outliers around 23 Jy, being baseline RT1-2
