Browse a table (MS, calibration table, image)
This task brings up a browser that can open and display any CASA table.
The tablename can be specified at startup, or any table can be loaded after
the browser comes up.
Parameters:
tablename -- Name of table file on disk (vis, calibration table, image)
default: none; example: tablename='ngc5921.ms'
mightedit -- If True disable the filtering options (below) and allow
editing the table. Warning: the GUI appears to ignore
whether the table tool is opened read-only - just be
aware that you should not edit filtered tables unless
you know what you are doing.
sortlist -- List of columns to sort by.
default: [] (none)
taql -- TaQL query string for prefiltering the table.
default: "" (none); example: taql="ANTENNA2 < 6"
skipcols -- Columns to NOT display.
default: [] (none); example: skipcols='feed1, feed2'
Some comments on using browsetable (see cookbook also):
Most often you will browse a measurement set. Either specify the vis name
as the tablename, or when the browser comes up,
click on <file> (upper left), then click on <open table>
If you want to look at sub-tables, use the tab table keywords along the
left side to bring up a panel with the sub-tables listed (Fig 3.8), then
choose (left-click) a table and View.
Note that one useful feature is that you can Edit any table and its
contents. Use the Edit tab (to the right of the file tab). Be careful
with this, and make a backup copy of the table before editing!
Use the Close Tables and Exit option from the Files menu to quit the
casabrowser.
To get a plot of two table values, click on tools, then click on plot 2D.
For example, to get a u-v plot, in the Plotter Option Gui,
set Rows: 0 to <Large Number>
X Axis: UVW Slice (set 0)
Y Axis: UVW Slice (set 1)
click 'Clear and Plot' on right.
For visibility plots
X Axis: TIME
Y Axis: DATA Slice Amplitude
click 'Clear and Plot' on right.
