Spectral-line case

Set the flux density of 3C 286 (field 1):

imgrS:=imager(filename='ngc5921.ms'); # Start the imager tool
imgrS.setjy(fieldid=1);               # Calculate & set flux density for 
                                      #  1328+307 (3C 286) to 14.76 Jy

After setjy is run you will get a report in the logger giving the status of the task along with the end results:

  Starting imager::setjy
    1331+30500002  spwid=  1  [I=14.76, Q=0, U=0, V=0] Jy, (Perley-Taylor 99)
  Finished imager::setjy

Check that the flux is actually set by using imgrS.plotvis (Fig. 1.10):

imgrS.setdata(fieldid=1);             # Setdata to 1331+305 (3C 286)
imgrS.plotvis(type='model');          # Plot model amplitudes vs uv distance
imgrC.done();                         # Close out the tool.
