y_baseline

property Workspace.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.
