ASAP SD task: coadd multiple scantables into one
  Keyword arguments:
infiles -- list of names of input SD dataset
antenna -- antenna name or id (only effective for MS input). 
fluxunit -- units for line flux
options: 'K','Jy',''
default: '' (keep current fluxunit of the first data in the infiles)

    >>> fluxunit expandable parameter
 telescopeparm -- the telescope characteristics
         options: (str) name or (list) list of gain info
         default: '' (none set)
         example: if telescopeparm='', it tries to get the telescope
                  name from the data.
                  Full antenna parameters (diameter,ap.eff.) known
                  to ASAP are
                  'ATPKSMB', 'ATPKSHOH', 'ATMOPRA', 'DSS-43',
                  'CEDUNA','HOBART'. For GBT, it fixes default fluxunit
                  to 'K' first then convert to a new fluxunit.
                  telescopeparm=[104.9,0.43] diameter(m), ap.eff.
                  telescopeparm=[0.743] gain in Jy/K
                  telescopeparm='FIX' to change default fluxunit
                  see description below

specunit -- units for spectral axis
options: (str) 'channel','km/s','GHz','MHz','kHz','Hz'
default: '' (=current)
example: this will be the units for masklist
frame -- frequency frame for spectral axis
options: (str) 'LSRK','REST','TOPO','LSRD','BARY',
         'GEO','GALACTO','LGROUP','CMB'
default: currently set frame in scantable
WARNING: frame='REST' not yet implemented
doppler -- doppler mode
options: (str) 'RADIO','OPTICAL','Z','BETA','GAMMA'
default: currently set doppler in scantable
scanaverage -- average integrations within scans
options: (bool) True,False
default: False
example: if True, this happens in read-in
For GBT, set False!
timeaverage -- average times for multiple scan cycles
options: (bool) True,False
default: False
example: if True, this happens after calibration

    >>>timeaverage expandable parameter
 tweight -- weighting for time average
         options: 'none' 
                  'var'   (1/var(spec) weighted)
                  'tsys'  (1/Tsys**2 weighted)
                  'tint'  (integration time weighted)
                  'tintsys'  (Tint/Tsys**2)
                  'median'  ( median averaging)
         default: 'none'

polaverage -- average polarizations
options: (bool) True,False
default: False

    >>>polaverage expandable parameter
 pweight -- weighting for polarization average
         options: 'none'
                  'var'  (1/var(spec) weighted)
                  'tsys' (1/Tsys**2 weighted)
         default: 'none'

outfile -- Name of output file
default: '' (scantable)
example:
outform -- format of output file
options: 'ASCII','SDFITS','MS','ASAP'
default: 'ASAP'
example: the ASAP format is easiest for further sd
         processing; use MS for CASA imaging.
         If ASCII, then will append some stuff to
         the outfile name
overwrite -- overwrite the output file if already exists
options: (bool) True,False
default: False
WARNING: if outform='ASCII', this parameter is ignored 



DESCRIPTION:

Task sdcoadd performs co-add multiple single dish spectral data given by
a list of spectral data file names in any of the following formats,
ASAP, MS2,SDFITS, and ASCII.
The units of line flux, the units of spectral axis, frame, and doppler
are assumed to be those of the first one in the infiles if not
specified.
timaverage and polaverage are used to perform time
and polarization averaging over scans on the co-added scantable before
saving to a file on disk.

WARNING for the GBT raw SDFITS format data as input:
SDtasks are able to handle GBT raw SDFITS format data since the 
data filler is available. However, the functionality is not well 
tested yet, so that there may be unknown bugs.
