HELP SECTION

TLCAL
Type: Task
Use:  Reads a JVLA telcal file and converts the complex gains and
      delays into an SN table.  This can then be applied to the CL
      table with CLCAL.  Note, if you run SETJY before running TLCAL,
      then you can use the SU table fluxes to scale the amplitudes of
      the known calibrators.  Then, after TLCAL, you may run GETJY to
      determine the fluxes of the secondary calibrators before running
      CLCAL to apply the SN table to the data set CL 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.
  DOAPPLY....If > 0, apply any fluxes found in the SU table to the
             amplitudes found by telcal when writing the SN values.
             HIGHLY RECOMMENDED: see above.
  ASDMFILE...(1) Last part of file name without the .GN at the end
                 ASDMFILE(2) must be blank (' ').  If it is not blank
                 the task will use the alternative below.

             The telcal files are located at the path name:
               /home/mchammer/evladata/telcal///
                !! ASDMFILE(1) !! .GN.
             The task will supply the /home/mchammer and year and
             month parts and the .GN.  You need to provide the file
             indentifier part such as C_quad1234_016.58274.92804802083
             which is the same as the identifier part needed by
             BDDFLIST and BDF2AIPS.  Be sure to omit the close quote
             so that case is preserved in the adverb value.

             An alternative if you have obtained the .GN file from
             mchammer already: Use both ASDMF(1) and ASDMF(2) to
             specify the full path to the .GN file (but leave off the
             .GN which the task will append).  This could be the same
             values for ASDMF as used by BDFLIST and BDF2AIPS if you
             put the .GN file in the same directory as the top
             directory of the SDM/BDF files.
