Polarimetry

A review is being made of imaging- and spectro-polarimetry using the FAPOL unit with ALFOSC. The idea is to unify the two modes as much as possible to make things more consistent and make it easier to switch between the modes. The telescope focus offsets for each element used in FAPOL will be measured such that the instrument set-up and use of polarimetry can be automated through the use of observing scripts.

The instructions about polarimetry in the observing cookbook will be updated and expanded to include spectro-polarimetry.
