6.16.1 FITS Image Export (exportfits)

To export your images to fits format use the exportfits task. The inputs are:

#  exportfits :: Convert a CASA image to a FITS file
imagename    =         ’’   #  Name of input CASA image
fitsimage    =         ’’   #  Name of output image FITS file
velocity     =      False   #  Use velocity (rather than frequency) as spectral axis
optical      =      False   #  Use the optical (rather than radio) velocity convention
bitpix       =        -32   #  Bits per pixel
minpix       =          0   #  Minimum pixel value
maxpix       =          0   #  Maximum pixel value
overwrite    =      False   #  Overwrite pre-existing imagename
dropstokes   =      False   #  Drop the Stokes axis?
stokeslast   =       True   #  Put Stokes axis last in header?
async        =      False   #  If true the taskname must be started using exportfits(...)

The dropstokes or stokeslast parameter may be needed to make the FITS image compatible with an external application.

For example,

exportfits(’ngc5921.demo.cleanimg.image’,’ngc5921.demo.cleanimg.image.fits’)
