SET WEIGHT

        LAS\SET WEIGHT Type

    Define the weighting to be used for summations. 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.

    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).
