0.1.74 msview

Requires:

Synopsis
View a visibility data set

Description

The msview task will display measurements in raster form. Many display and editing options are available.

Executing the msview task will bring up a display panel window, which can be resized. If no data file was specified, a Load Data window will also appear. Click on the desired measurement set,and the rendered data should appear on the display panel.

A Data Display Options window will also appear. It has drop-down subsections for related options, most of which are self-explanatory.

The state of the msview task – loaded data and related display options – can be saved in a ’restore’ file for later use. You can provide the restore filename on the command line or select it from the Load Data window.

See the cookbook for more details on using the msview task.
