What was wrong.
Also filter non-linearities. Calibrate with one filter but use another.

The plan
Standardised instrument characterisation and calibration.
Standardised central data processing and quality assurance.
This increase of uncertainty is
of the same order as the absolute calibration uncertainty
invisible in the output data and data base
undetectable in ”blind-test” data submitted in an intercomparison campaign
We want
Leading to
Consistent near real time products of O3, Spectral UV and AOD.
