Phase retardation caused by the Gr6gory-Coud6 telescope at Locarno is determined empirically and compared with calculations. Good agreement is found for a proper retardation angle A = 16 ~ for each of the two plane mirrors in the telescope. The praxis of compensation by means of two 2/8-plates (Bow

The usefulness of magnetically sensitive iron lines Fe )`5250.2, 6173.3 and 6302.3 for solar polarimetry is investigated. The line-to-continuum absorption coefficient ~/0 for Fe 25250.2 depends strongly on temperature variations. Thus a photospheric calibration of polarimeter signals cannot be used
