​

                Task for plotting and interacting with visibility data and

                calibration tables.

​

                Plotms provides a variety of axis choices (including data column)

                along with selection, averaging, and transformation options for

                MeasurementSets.  Flag extension parameters are also available for

                interactive flagging operations in the plotter.

                All of the provided parameters can also be set using the GUI once

                the application has been launched or through the plotms tool (pm).

​

                Most of the basic plotms functions will work for calibration tables.

                The correlation selection string may be used to select polarization

                in a cal table, including ratio plots ("/").  The antenna selection

                string is used to select antenna1 only, rather than baselines as in

                an MS. When plotting parameterized CalTables, such as delays, antpos,

                gaincurve, or opacity, plotms will currently just plot the simple

                parameters contained in the table, not the effective amplitudes or

                phases sampled at observing times, frequencies etc.  BPOLY and

                GSPLINE tables are supported but interactive flagging is not allowed.

                Features currently unsupported for CalTables include averaging,

                transformations (velocity conversions, etc.), and some axis and

                selection options which do not exist in these tables. In the plotms

                GUI, many options irrelevant for CalTables are not hidden when

                interacting with a CalTable, and such settings will be ignored (when

                benign) or cause an error message.
