    keyword=New settings for Q-wave plates

    Since the latest tuning of the rotatable Q-wave at running condition
    seems to help a lot for the target polarization. I did a finer tuning and
    mass an access to adjust the fixed Q-wave plates as well:

    The new settings are the following:

    Motor 1426 = plate #5 on S wave upstream facing upstream -> 101 Degree (46)
    Motor 1423 = plate #6 on S wave downstream facing upstream -> 137 Degree (83)

    plate #15 on P wave upstream facing downstream -> -25 Degree (46)
    plate #16 on P wave downstream facing downstream -> 8 Degree (83)
