16 exportfits ---- Convert a CASA image to a FITS file
19 CASA-produced images can be exported as FITS files for transporting to
20 other software packages or publication.
21 No subimaging of the fits image can be made with this task.
22 The spectral reference frame can be changed prior to export using the
23 task imreframe.
25 --------- parameter descriptions ---------------------------------------------
27 imagename Name of input CASA image
28 Default: none
30 Example: fitsimage='3C273XC1.image'
31 fitsimage Name of output image FITS file
32 Default: none
34 Example: fitsimage='3C273XC1.fits'
35 velocity Use velocity (rather than frequency) as spectral axis
36 Default: False
37 Options: False|True
38 optical Use the optical (rather than radio) velocity convention
39 Default: False
40 Options: False|True
41 bitpix Bits per pixel
42 Default: -32
44 Example: bitpix=16
45 minpix Minimum pixel value (if minpix > maxpix, value is automatically determined)
46 maxpix Maximum pixel value (if minpix > maxpix, value is
47 automatically determined)
48 Default: -1
49 overwrite Overwrite output file if it exists?
50 Default: False
51 Options: False|True
52 dropstokes Drop the Stokes axis?
53 stokeslast Put Stokes axis last in header?
54 Default: True
55 Options: True|False
56 history Write history to the FITS image?
57 Default: True
58 Options: True|False
59 dropdeg Drop all degenerate axes (e.g. Stokes and/or Frequency)?
60 Default: False
61 Options: False|True
