Workspace Variable y_baseline

The baseline of y.

In retrieval "lingo", the baseline is an addiative disturbance of
the measured spectrum. That is, it can be seen as a shift (from zero)
of measurement. Reflections inside microwave receivers is one source to
a baseline off-set.

So far there is no module in ARTS that actually tries to physically model
any baseline effect. y_baseline is just used as a pure fitting parameter
in retrievals. One example on method to include a baseline fit is 
jacobianAddPolyfit.

If the baseline is totally constant, it is allowed to set y_baseline
to have length one, with this element set to the baseline value.

Usage: Output of retrievals.

Unit:  Same as applied for y.

Group: Vector
