SET WEIGHT

        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.

    In case of a folded frequency switch spectrum,  the  spectrum  is  given
    twice more weight (as if the integration time was twice longer).

    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).
