30may16: Alfa calibration scans, rotation angle


Compare to may14 results after re-installation
Compare to may15 results after re-installation

    Alfa was reinstalled in the dome on 13may16  after being worked on in the lab. Spider scans (heiles calibration scans) were taken with alfa on 30may16 using beams0..6
This data was taken with model18A  and with the tiedowns active.

The setup:

Calibration run results:

The plots show the   calibration results (.ps) (.pdf):

Fitting for rotation angle error:

    Part of the pointing error could come from the alfa rotation angle being off. To test for this :
