imagerwizard - Function

Wizard for synthesis imaging

Synopsis imagerwizard() include "imagerwizard.g"

Description

imagerwizard provides a GUI for making a clean image from a MeasurementSet with the minimum of user intervention. It is based on the table, imager, ms, and wizard Display is performed using the viewer.

In imagerwizard, the user is walked through a number of steps using a simple GUI:

Either a MeasurementSet or a FITS file can be specified. If the latter, it is converted to a MeasurementSet using the fitstoms constructor of the ms tool.
The spectral windows are listed and the user asked to select one for imaging.
The user is asked to select values for certain control values. Note that all of these can be left as the default values (i.e. mostly unset values).
A clean image of the entire primary beam is made from the inner 33% of the uv plane using 1000 Clean iterations.
The resulting clean image is displayed and the user asked to zoom the region of interest.
The Clean is repeated at full resolution with all the data, cleaned down to 3 $\sigma$ where the noise is estimated as three times the Stokes V rms.
The final image is displayed.

Typically, imagerwizard works well for a quick look at all synthesis data except VLBI but you may want to use imager directly for the final image.

During the cleaning stage, some of the relevant Glish commands for imager and the other tools are displayed. Note that these are slightly more verbose than you would type but should be executable. Not all commands are displayed, obviously. In particular, we have not shown those related to the operation of imagerwizard. Hence all the command you see are ones that you might plausibly use during data reduction. The commands are written to a file called 'imagerwizard_commands.g' in the current directory.

Note that if you don't have a dataset, then the function imagermaketestms() can be used to make a copy of the standard test MeasurementSet 3C273XC1.ms. The button Make test MS (in stage 1) will accomplish the same thing.

Example

include 'imagerwizard.g'
imagermaketestms()		# To make the standard MS 3C273XC1.ms
imagerwizard()			# To start the GUI
