[daip] offset calibrator

[Amy Mioduszewski]

Hi Geoff,

As far as we can all tell you are doing things correctly.  Since
the image of the calibrator looks good then CLCOR and CALIB did
the right thing.  I have 2 thoughts: 1) what does the target look
like before you apply the calibration for SgrA*? and 2) have you
checked the CL table that you apply to the target carefully, do
the phases etc, look reasonable and consistent with the SN table
out of CALIB?

Cheers,

Amy
