0.1.22 exportfits

Requires:

Synopsis
Convert a CASA image to a FITS file

Description

CASA-produced images can be exported as FITS files for transporting to other software packages or publication. No subimaging of the fits image can be made with this task. The spectral reference frame can be changed prior to export using the task imreframe.

Arguments


Inputs
imagename	Name of input CASA image
	allowed:	string
	Default:
fitsimage	Name of output image FITS file
	allowed:	string
	Default:
velocity	Use velocity (rather than frequency) as spectral axis
	allowed:	bool
	Default:	False
optical	Use the optical (rather than radio) velocity convention
	allowed:	bool
	Default:	False
bitpix	Bits per pixel
	allowed:	int
	Default:	-32
minpix	Minimum pixel value (if minpix > maxpix, value is automatically determined)
	allowed:	any
	Default:	variant 0
maxpix	Maximum pixel value (if minpix > maxpix, value is automatically determined)
	allowed:	any
	Default:	variant -1
overwrite	Overwrite pre-existing imagename
	allowed:	bool
	Default:	False
dropstokes	Drop the Stokes axis?
	allowed:	bool
	Default:	False
stokeslast	Put Stokes axis last in header?
	allowed:	bool
	Default:	True
history	Write history to the FITS image?
	allowed:	bool
	Default:	True
dropdeg	Drop all degenerate axes (e.g. Stokes and/or Frequency)?
	allowed:	bool
	Default:	False

Example

exportfits(imagename=’NGC3256-continuum.image’, fitsimage=’NGC3256cont.fits’, history=False)
