Imaging the result

Once the simulated visibilities are written then we can make an image. Click the TDL Exec button and expand the imaging options. As usual we're imaging the DATA column (which should be the only column that contains anything), averaging all the channels and imaging a 30 x 30 arcminute region.

Click 'make a dirty image' and it should return something like the image below.

Another nice way to see the effect is to image all the channels and perform no averaging. If you do this with 1024 x 1024 pixel frames then the FITS file is 257 MB which I don't really want to add to the PURR log, so there's an AVI available in the data products below.
