| |
| A plotter/interactive flagger for visibility data.
| |
| | |
| Task for plotting and interacting with visibility data. A variety
| |
| of axes choices (including data column) along with MS selection and
| |
| averaging options are provided for data selection. Flag extension
| |
| parameters are also available for flagging operations in the plotter.
| |
|
| |
| All of the provided parameters can also be set using the GUI once
| |
| the application has been launched. Additional and more specific
| |
| operations are available through the GUI and/or through the plotms
| |
| tool (pm).
| |
|
| |
| | |
