Basic Information on uvcover

Task: uvcover
Purpose: Display uv coverage
Categories: uv analysis

UVCOVER displays UV coverage. Although the W coordinate is read
(if present) it is not plotted. The program UVPLOT with keyword
'axis=uv,vc' does exactly the same as UVCOVER, but allows more
selection *and* does not plot flagged data. Hence this
program is deprecated.

Key: vis
This is the normal keyword for an input visibility dataset. There
is generally no default input name. Some tasks allow multiple input
datasets (with wildcards supported, such as an asterisk). Other tasks
can handle only a single dataset at a time.

Key: device
This keyword is used to specify the plotting device. It uses
the normal PGPLOT format of

  file/type

 or

  device/type

Usually there exists a default file name or device name.
The part after the slash gives the plotter type. Examples of the
type are:

  xs    X-windows output. This window is resizeable and
        persistent. Prepending a number allows you to use multiple
        windows, e.g. 1/xs, 2/xs etc.
  xd    X-windows output. A transient window that disappears
        when your task exists.
  ps    Postscript (landscape mode).
  vps   Postscript (portrait mode).
  cps   Color postscript (landscape mode).
  gif   gif files. Only supported with g77, not gfortran.
  vcps  Color postscript (portrait mode).
  tek   Tektronix 4010 or equivalent.
  xterm Xterm window (better for simple plots over slow X links).

A `?' as device name generates a complete list of the recognized
types (which will most likely vary from system to system).

Files created for hardcopy devices must be spooled to the printer
separately. The command needed for this is site and device specific.
