        LAS\SET WEIGHT Type

    Define  the weighting to be used in the averaging engine (AVERAGE, ACCU-
    MULATE, STITCH), in the command TABLE,  and  in  the  command  UV_TABLE.
    Choices are:
      T[ime],       for Time*abs(Fres)/(Tsys**2) (spectrum) or
                        Time*abs(Width)/(Tsys**2) (continuum),
      S[igma],      for 1/Sigma**2,
      E[qual],      for equal weights,
      A[ssociated], to use the Associated Array named "W" from each input
                    spectrum. "W" provides one weight value per channel.

    The  default  is  TIME.  Sigma is not recommended unless you just made a
    baseline fit before. Equal weight behaves differently in  AVERAGE/STITCH
    and ACCUMULATE (which produces the sum).
