For some time we have consider to set-up a simple system to archive the SOFIN data. In principle the data for a whole run can be saved in one go (probably on only one DVD). The main issues to sort-out are the naming of the files (which should be something like SOddmmyyyy.fits to comply with our naming convention) and the names of the headers.
Ilya Ilyin (Potsdam) who normally performs the observations was contacted and we are discussing the possibility to include his data and their FITS headers in our general system. The plan is that he will bring all his archive data the next time he comes to observe so we can look atthis in more detail.
