Notes. The first row is the 850 
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.
