\tablefoot{The first row is the 850~$\mu$m flux from LABOCA on APEX, which contains also lines. The next rows are the baseline levels at the given frequencies in HIFI bands~1a, 1b, 2a and~4b. The baseline level of HIFI is a reliable continuum measurement, since it is as strong as saturated absorption lines and compares well with ground-based continuum data.}
