The program’s main window shows a time-frequency plot (dynamic spectrum) of a selected baseline and/or polarization, and from there it is possible to analyse the data in various ways.
A few of its key features:
Analyse Casa Measurement Sets, UVFits files and other supported formats;
Make time-frequency diagrams and other cuts through the data;
Export plots to pdfs (interactively or scripted);
Execute and tweak flagging strategies;
Visualize the uv plane and/or image plane for selected data.
A list of possible command line options can be obtained by running
rfigui --help. There are some options available to create images from the command line, see the page on scripting.
