Selfcalibration after subtracting sources
Posted: Thu Sep 22, 2016 2:47 am
Hello,
I have noticed that I lose the selfcalibration of a uv-data if I subtract components using the task UVMODEL.
The tricky part is that I subtract from the uv-data only the clean components of the image created by using only the longest baselines of my antenna array.
Then I image this new source-subtracted uv-data and when I use the clean components of this new image to self-calibrate, the solutions are not as good (some artifacts re-appear) as when
I self-calibrate the original uv-data .
Which clean components should I use to selfcalibrate the new uv-data?
Thanks!
