Polarimetric Standard BD -14 4922:

Observations without half wave plate at 0 and 45 degree Cassegrain rotator
position. Check if the deviation of the retarder plate zero angle derived
from  BD -14 4922 is a result of false meassurement of Hiltner.
Preliminary reduction shows that literature value of the polarisation angle
of BD -14 4922 is completely wrong.

Additional observations with the retarder plate (angles 0,..67.5 degree)
at Cass rotator 0,45 degrees. To frame COM23_IPOL.5.fits the frames are
overexposed!!!
