Example The following example shows the quickest way to make a CLEAN image and display it. Note that this can be more easily done from the ??.
include ’imager.g’
# # First make the MS from a FITS file: # m:=fitstoms(msfile=’3C273XC1.MS’, fitsfile=’3C273XC1.FITS’); m.close(); # # Now make an imager tool for the MS # imgr:=imager(’3C273XC1.MS’) # # Set the imager to produce images of cellsize 0.7 and # 256 by 256 pixels # imgr.setimage(nx=256,ny=256, cellx=’0.7arcsec’,celly=’0.7arcsec’); # # Wait for results before proceeding to the next step # dowait:=T # # Make and display a clean image # imgr.clean(niter=1000, threshold=’30mJy’, model=’3C273XC1.clean.model’, image=’3C273XC1.clean.image’) dd.image(’3C273XC1.clean.image’) # # Fourier transform the model # imgr.ft(model=’3C273XC1.clean.model’) # # Plot the visibilities # imgr.plotvis() # # Write out the final MS and close the imager tool # imgr.close() |
