INTERPOL
Type: Adverb  (String*4)
Use:  Standard data selection adverb; used to specify the
      interpolation function to be applied to the gain table:
      In CLCAL:
         '    ' = linear vector interpolation with no SN smoothing.
         '2PT ' = linear vector interpolation with no SN smoothing.
         'SELF' = do 2PT but only using SN entries from the same
                  source.  (New mode starting 20 April 2004.)
         'SELN' = Use only SN solution from same source which is
                  closest in time.  (This mode was called SELF before
                  20 April 2004.)
         'POLY' = Fit a polynomial to the SN rates and delays.  Use
                  the integral of the rate polynomial for the phases.
         'SIMP' = Simple linear phase connection between SN phase
                  entries, assumes phase difference less than 180 deg.
         'AMBG' = Linear phase connection using rates to resolve phase
                  ambiguities.
         'CUBE' = As AMBG but fit third order polynomial to phases and
                  rates.
      This adverb is only relevant when the data being operated
      on has an associated gain table.
Null value:  '    ' see above.
