Convert a CASA visibility data set to a UVFITS file:

This task writes a UVFITS file, a general format data set used
to transfer data between different software systems.  It is
written in floating point format.  Different programs have different
restrictions on what forms of UVFITS files they will use, especially
whether they will accept multiple sources and/or spectral windows in
the same file.  See the spw, multisource, and combinespw descriptions
below.

Keyword arguments:
vis -- Name of input visibility file
default: none;  example: vis='ngc5921.ms'
fitsfile -- Name of output UV FITS file
default: none;  example='3C273XC1.fits'
datacolumn -- Visibility file data column
default: => 'corrected'; example: datacolumn='model'
Options: 'data' (raw),'corrected','model','weight'
field -- Select field using field id(s) or field name(s).
  [run listobs to obtain the list id's or names]
       default: ''=all fields
       If field string is a non-negative integer, it is assumed a field index
       otherwise, it is assumed a field name
       field='0~2'; field ids 0,1,2
       field='0,4,5~7'; field ids 0,4,5,6,7
       field='3C286,3C295'; field named 3C286 adn 3C295
       field = '3,4C*'; field id 3, all names starting with 4C
spw -- Select spectral window/channels 
 type 'help par.selection' for more examples.
       spw='0~2,4'; spectral windows 0,1,2,4 (all channels)
       spw='<2';  spectral windows less than 2 (i.e. 0,1)
       spw='0:5~61'; spw 0, channels 5 to 61, INCLUSIVE
       spw='*:5~61'; all spw with channels 5 to 62
       spw='0,10,3:3~45'; spw 0,10 all channels, spw 3, channels 3 to 45.
       spw='0~2:2~6'; spw 0,1,2 with channels 2 through 6 in each.
       spw='0:0~10;15~60'; spectral window 0 with channels 0-10,15-60
         NOTE ';' to separate channel selections
       spw='0:0~10^2,1:20~30^5'; spw 0, channels 0,2,4,6,8,10,
     spw 1, channels 20,25,30
antenna -- Select data based on antenna/baseline
       default: '' (all)
       If antenna string is a non-negative integer, it is assumed
  an antenna index
 otherwise, it is assumed as an antenna name
       antenna='5&6'; baseline between antenna index 5 and index 6.
       antenna='VA05&VA06'; baseline between VLA antenna 5 and 6.
       antenna='5&6;7&8'; baseline 5-6 and 7-8
       antenna='5'; all baselines with antenna index 5
       antenna='05'; all baselines with antenna name '05', vla antenna
       antenna='5,6,10'; all baselines with antennas 5, 6 and 10
timerange  -- Select data based on time range:
       default = '' (all); examples,
       timerange = 'YYYY/MM/DD/hh:mm:ss~YYYY/MM/DD/hh:mm:ss'
       Note: if YYYY/MM/DD is missing dat defaults to first day in data set
       timerange='09:14:0~09:54:0' picks 40 min on first day
       timerange='25:00:00~27:30:00' picks 1 hr to 3 hr 30min on next day
       timerange='09:44:00' data within one integration of time
       timerange='>10:24:00' data after this time
avgchan -- Channel averaging width (value > 1 indicates averaging)
default =>1; example: avgchan=3
output data will average channels in groups of three.
multisource -- Write in multi-source format
default: => True;
   false if one source is selected
True works with AIPS, but not difmap.
combinespw -- If True, export the spectral windows as IFs.
      Otherwise multiple windows will use multiple FREQIDs.
default: =>  True;
   all spectral windows must have same shape.
True is recommended for AIPS, and mandatory for difmap.
padwithflags -- If True, and combinespw is True, fill in missing
        data as needed to fit the IF structure.  This is
        appropriate if the MS had a few frequency-dependent
        flags applied, and was then time-averaged by split, or
        when exporting for use by difmap.  If the spectral
        windows were observed at different times,
        padwithflags=True will add a large number of flags,
        making the output file significantly longer.  It does
        not yet support spectral windows with different widths.
writestation -- Write station name instead of antenna name
default: True;
writesyscal -- Write GC and TY tables
default: => False; Not yet available
async --  Run asynchronously
default = False;
