   TKSLICE.......Verb to display slice file directly on TEK.
   TVACOMPS......Verb to add slice model components directly on TV
                 graphics.
   TVAGUESS......Verb to re-plot slice model guess directly on TV
                 graphics.
   TVAMODEL......Verb to add slice model display directly on TV graphics.
   TVARESID......Verb to add slice model residuals directly on TV
                 graphics.
   TVASLICE......Verb to add a slice display on TV graphics from slice
                 file.

Procedures:
   FXALIAS.......Least squares fit aliasing function and remove.  EDROP
                 is the highest channel in the calibrator average.
Tasks:
   EXTAB.........Exports AIPS table data as tab-separated text.
                 Additional elements through EDROP are printed.
   FIXAL.........Least squares fit aliasing function and remove.  EDROP
                 is the highwest channel in the calibrator average.
   PRTAB.........Prints any table-format extension file.  Additional
                 elements through EDROP are printed.
   SL2PL.........Task to convert a Slice File to a Plot File.
   SLFIT.........Task to fit gaussians to slice data.
   UVFIT.........Fits source models to uv data.  EDROP is misused to
                 specify a tolerance level for the fit cutoff.
   UVGIT.........Fits source models to uv data.  EDROP is misused to
                 specify a tolerance level for the fit cutoff.
   VLBIN.........Task to read VLBI data from an NRAO/MPI MkII correlator.
                 EDROP channels at the end of each spectrum are
                 omitted.
