Hi Mark,

   Yes, I did baseline-based calibration.   I hope to look at the closure problem more closely.   The closure error was significantly reduced after passband calibration was applied and the continuum was regenerated. Maybe a really careful passband calibration will make the closure error go away entirely.

    Hi Taco,

    Did you do baseline-based calibration?   The fact that you saw significant closure errors suggests that would be important to do, and I did *not* do that with what I showed last week.  So, I think it is quite likely that my plots showed such differences (in both amplitude and phase) due to my not calibrating the closure error, which I assume you did.

    Thanks for looking at the data!
