Hi John,

Yes, I'm not surprised DBCON worked. I'm sure next time you'll do it before transfer..
On the line contamination, you can just flag those channels and proceed, assuming it is only a reasonably small part of the bandwidth that you flag (as you need enough S/N to determine your solution, but that usually is fine). You are determining a phase solution (single number per interferometer that ends up in your solution table) over that bandwidth with a point source and if the flagged channels remove the extended line emission from your input data you should be all right using a point source model. You can always check after flagging in the uv-dist vs amp plot to determine if you got all extended emission out before CALIB/gaincal.
