Notes. First column: identifier of the observation. Second column: date and time of the observation in UTC. Third column: exposure time in seconds for each of the two measurements of each run, (I,  Q/I,  V/I) and (I,  U/I,  V/I). Fourth column: cosine of the heliocentric angle. Fifth column: standard deviations of the noise per pixel in the polarization images. Last column: slit position on the solar disk. The plage at the east limb was not visible until May 31. For this reason, the observations of the June 02 has been differentiated from the ones on May 31.
