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.

Example
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.

triple ampersands (&&&) to select only
auto-correlations. E.g.:
