16 exportfits ---- Convert a CASA image to a FITS file 

17 

18  

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. 

24 

25 --------- parameter descriptions --------------------------------------------- 

26 

27 imagename Name of input CASA image 

28 Default: none 

29  

30 Example: fitsimage='3C273XC1.image' 

31 fitsimage Name of output image FITS file 

32 Default: none 

33  

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 

43  

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
