Simulating and imaging

Logged on 06/29/2009 01:00:47 PM

If all went well then the imager should have run in the background, it will have hopefully invoked your FITS viewer and you will have seen an image.

Close the viewer, return to the MeqBrowser and click the 'TDL Exec' button to bring up the runtime options.

I'm going to write the visibilities to the DATA column of this MS, so select 'custom' for the 'Output MS column' option and enter 'DATA'.

It's worth noting that whatever column you have selected will be overwritten or modified without warning and without an undo button as soon as you click the 'simulate MS' button.

Once you do click this button it will execute the tree.

Now let's image the simulation. Click the 'TDL Exec' button and set up the imaging options as show below. We're averaging all the channels here and imaging a half-degree field. If all's gone well then you should see the image below.

This simulated Measurement Set is open challenge number 1.
