SET ALIGN

        LAS\SET ALIGN Type Range

    Defines  the way the spectra to be added are aligned (Type) and combined
    (Range). Possible combinations are:
    Type: C[hannel]      for spectra and drift
          V[elocity]     for spectra only
          F[requency]    for spectra only
          P[osition]     for drift only
    Range: I[ntersect] or C[omposite]
    Default is SET TYPE C I. Note: This means that continuum drifts in oppo-
    site directions are not properly added: ALIGN Position must be specified
    for that.
