UV2TB
Task:  This task writes autocorrelation spectra into a table of
       type AS.  Each autocorrelation visibility in the input uv
       data is written into a separate row of the table.

Adverbs:
  INNAME.....Input UV file name (name).      Standard defaults.
  INCLASS....Input UV file name (class).     Standard defaults.
  INSEQ......Input UV file name (seq. #).    0 => highest.
  INDISK.....Disk drive # of input UV file.  0 => any.
  SOURCES....Source list.  '  ' or '*' = all;
             a "-" before a source name means all except ANY
             source named.
  QUAL.......Only sources with a source qualifier number in the
             SU table matching QUAL will be used if QUAL is not
             -1.
  CALCODE....Sources may be selected on the basis of the
             calibrator code given in the SU table.
                  '    ' => any calibrator code selected
                  '*   ' => any non blank code (cal. only)
                  '-CAL' => blank codes only (no calibrators)
                  anything else = calibrator code to select.
             NB: The CALCODE test is applied in addition to the
             other tests, i.e. SOURCS and QUAL, in the
             selection of sources to process.
  TIMERANG...Time range of the data to be copied. In order:
             Start day, hour, min. sec,
             end day, hour, min. sec. Days relative to ref.
             date.
  STOKES.....The Stokes type to accept:
             'I'  ('  ' => 'I')
              If the data is RR,LL,RL,LR the following are
              valid: 'RR', 'LL', 'RL', 'LR'
              If the data is in the form of IQUV then the
              following are valid: 'Q', 'U', 'V'
  SELBAND....Bandwidth of data to be selected. If more than
             one IF is present SELBAND is the width of the
             first IF required. Units = kHz. For data which
             contain multiple bandwidths/frequencies the task
             will insist that some form of selection be made
             by frequency or bandwidth.
  SELFREQ....Frequency of data to be selected. If more than
             one IF is present SELFREQ is the frequency of the
             first IF required. Units = MHz.
  FREQID.....Frequency identifier to select (you may determine
             which is applicable from the OPTYPE='SCAN' listing
             produced by LISTR). If either SELBAND or SELFREQ
             are set, their values overide that of FREQID.
             However, setting SELBAND and SELFREQ may result in
             an ambiguity.  In that case, the task will request
             that you use FREQID.
  BIF........First IF to copy. 0=>all.
  EIF........Highest IF to copy. 0=>all higher than BIF
  BCHAN......First channel to copy. 0=>all.
  ECHAN......Highest channel to copy. 0=>all higher than BIF
  SUBARRAY...Subarray number to copy. 0=>all.
  DOCALIB....If true (>0), calibrate the data using information in the
             specified Cal (CL) table for multi-source or SN table for
             single-source data.  If > 1.5, also calibrate the weights
             (new for VLA, normal for VLBI).
  GAINUSE....Version number of the CL table to apply to
             multisource files or the SN table for single
             source files.  0 => highest.
  DOPOL......If > 0 then correct data for instrumental
             polarization as represented in the AN table.  This
             correction is only useful if PCAL has been run or
             feed polarization parameters have been otherwise
             obtained. See HELP DOPOL for available correction
             modes.
  BLVER......Version number of the baseline based calibration
             (BL) table to appply. <0 => apply no BL table,
             0 => highest.
  FLAGVER....specifies the version of the flagging table to be
             applied. 0 => highest numbered table.
             <0 => no flagging to be applied.
  DOBAND.....If true (>0) then correct the data for the shape of the
             antenna bandpasses using the BP table specified by BPVER.
             The correction has five modes:
             (a) if DOBAND=1 all entries for an antenna in the table
             are averaged together before correcting the data.
             (b) if DOBAND=2 the entry nearest in time (including
             solution weights) is used to correct the data.
             (c) if DOBAND=3 the table entries are interpolated in
             time (using solution weights) and the data are then
             corrected.
             (d) if DOBAND=4 the entry nearest in time (ignoring
             solution weights) is used to correct the data.
             (e) if DOBAND=5 the table entries are interpolated in
             time (ignoring solution weights) and the data are then
             corrected.
  BPVER......Specifies the version of the BP table to be applied
             plotted (if APARM(8)=2) or applied (if DOBAND > 0
             and APARM(8) .NE. 2). 0 => highest numbered table.
             <0 => no bandpass correction to be applied.
  SMOOTH.....Specifies the type of spectral smoothing to be
             applied to a uv database . The default is not to
             apply any smoothing. The elements of SMOOTH are
             as follows:
             SMOOTH(1) = type of smoothing to apply:
               0 => no smoothing
               1 => Hanning
               2 => Gaussian
               3 => Boxcar
               4 => Sinc (i.e. sin(x)/x)
             SMOOTH(2) = the "diameter" of the function, i.e.
               width between first nulls of Hanning triangle
               and sinc function, FWHM of Gaussian, width of
               Boxcar. Defaults (if < 0.1) are 4, 2, 2 and 3
               channels for SMOOTH(1) = 1 - 4.
             SMOOTH(3) = the diameter over which the convolving
               function has value - in channels.
               Defaults: 1, 3, 1, 4 times SMOOTH(2) used when
               input SMOOTH(3) < net SMOOTH(2).
  OUTVER.....Output AS table version number. 0=>new table.
               If the table already exists then new data will be
               appended to the end of the table.
