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.
