Examples

To generate a spectral line cube with 500 channels selected from channel 200 to 700:

spw='0'
pol='XX'
src='Moon'

sdimaging(infiles='mydata.ms',
    spw=spw,
    nchan=500,
    start='200',
    width='1',
    cell=['30.0arcsec','30.0arcsec'],
    outfile='mydata.ms.im',
    imsize=[80,80],
    gridfunction='GAUSS',
    gwidth='4arcsec',
    stokes=pol,
    ephemsrcname=src)

 

The start parameter can be specified in different units:

start=100 (mode='channel')
start='22.3GHz' (mode='frequency')
start='5.0km/s' (mode='velocity')

 

The parameter ephemsrcname can be set to a solar system object:

ephemsrcname ='MERCURY'
