Polarimetry

A remaining issue has been the status of the FAPOL polarimetry unit with respect to our integrated data base system. In particular, to have the correct name of the retarder plate that is mounted to appear both on the display of the user interface and in the FITS header of the observing data, this has to be entered in 2 separate and unrelated places. The user interface was changed such that in both cases the status is obtained from the data base.
