Requires:

Synopsis
A plotter/interactive flagger for visibility data.

Description

Task for plotting and interacting with visibility data. Limited support for caltable plotting is also included as of CASA v4.1.

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).

Most basic functions (plotting, iteration, locate, flagging) will work for most CalTables. Parameterized CalTables (delays, antpos, gaincurve, opacity), will, at best, 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 not yet supported. Features currently unsupported for CalTables include Averaging, Transformations (velocity conversions, etc.), and some details of selection (channel and polarization selection are not yet enabled) and axes choices (geometry options are not yet enabled). In the plotms gui, many options irrelevant for CalTables are not yet hidden when interacting with a CalTable, and such settings will be ignored (when benign) or cause an error message.
