DOACOR
Type: Adverb  (Logical,  > 0  =>  true)
Use:  True (> 0) means to include autocorrelation data in some
      operation.  False (<= 0) means to omit autocorrelation data.
Null value:  false (-1).
Tasks:
   ALVPR.........Prints statistics on the Allan Variance of a UV data
                 set.
   AVGWT.........Computes the average visibility weight of the included
                 data.
   AVSPC.........Averages uv-data in the frequency domain.
   BPWGT.........Calibrates data and scales weights by bandpass
                 correction.
   DIFRL.........Divides the RR data by LL data.
   FGCNT.........Counts samples comparing two flag tables.
   FILLM.........Reads VLA on-line/archive format uv data tapes
                 (post Jan 88).
   FLOPM.........Reverses the spectral order of UV data, can fix VLA
                 error.
   FRPLT.........Task to plot fringe rate spectra.
   FUDGE.........Modifies UV data with user's algorithm: paraform task.
   LISTR.........Prints contents of UV data sets and assoc. calibration
                 tables.
   NOIFS.........Makes all IFs into single spectrum.
   PHSRF.........Perform phase-referencing within a spectral line
                 database.
   REWAY.........Computes weights based in rms in spectra.
   SPMOD.........Modify UV database by adding a model with spectral
                 lines.
   SUFIX.........Modifies source numbers on uv data.
   SWAPR.........Modifies UV data by swapping real and imaginary parts.
   UVAVG.........Average or merge a sorted (BT, TB) uv database.
   UVBAS.........Averages several channels and subtracts from uv data.
   UVFRE.........Makes one data set have the spectral structure of
                 another.
   UVLIN.........Fits and removes continuum visibility spectrum, also
                 can flag.
   UVLSD.........Least squares fit to channels and divides the uv data.
   UVLSF.........Least squares fit to channels and subtracts from uv
                 data.
   UVMOD.........Modify UV database by adding a model incl spectral
                 index.
   UVMTH.........Averages one data set and applies it to another.
   UVPLT.........Plots data from a UV data base in multiple ways.
   UVPRT.........Prints data from a UV data base with calibration.
   UVRFI.........Mitigate RFI by Fourier transform or fitting the
                 circle.
   VH2RL.........Converts from linear to circular polarization and vice
                 versa.
   VHMOD.........Compute linear polarization point source model, applies
                 to data.
   XYMOD.........Compute linear polarization point source model, applies
                 to data.
