You can subtract a model (point source, gaussian) or a clean comp.
model from a uv dataset with UVSUB.

You can use DBCON to concatenate datasets.

Yea, the only way you (as far as I know) can deal with a variable core is
to subtract the core from each dataset with UVSUB and then concatenate them.

How close are the epochs, the jet in SS433 changes a lot with time too.
