With the recent acquisitions of the first FODIS data, we attempted to process some using azspec and appear to have a problem. By comparison with the solar spectrum (​http://fsf.nerc.ac.uk/img/g37_grph.gif) and a Caligeo processing of the same line, there is a clear discrepancy. Image below shows a worst case selection of the azspec FODIS output.
