Hi all,
I'm attempting to make a visibility plot (example attached) for my target. I know uvamp can be used for this, but I was hoping to play around with the data myself (ie different bins, chi squared analysis) in python and need it in a data format with u(lamda),v(lamda),real(jy),imaginary(jy),w(lamda) information. Is it possible to output this kind of file?
Thanks,
Brodie

Re: Visibility Plots
Hi Brodie,
I don't think there is a task that does exactly that.
A more laborious way to get what you want is to run uvplt with options=log for axis=uu,vv and then for axis=real,imag and then reading both log files into python, discarding the non data lines at the start.
You may want to average in time or freq to reduce the amount of data.
I can't see a way to get at w this way.
Cheers,
Mark
