Measurement of CalUnitDx spots

On Sep 28th MPE team took some pictures of the position of the CalUnitDx spots on the LgswTableDx. See email from Sebastian from "calib source spots on wfs table" of 28 Sep 2014.

The photos are available here.

The target grid size is 2mm. The position of the target for each pic is summarized in this excel file.

A description of pics up to 9094 is:

Setup was:
we used the Arcetri alignment tools: a rail attached to the reference points on the table and the angle piece to define the center. We attached a sheet metal to this location and Matthias has printed us a target.
The target center is therefore on the center of the wfs-as -aligned. it shows a circle with 159.xx mm radius. Accuracy of the printed target has been determined to be -0.5mm. 120° lines are aligned on the target. dxf file of the target can be delivered.

Telescope has been put into Luci@argos position. which is:
X: -5.0
Y: -5.45
Z:4.3
Rx-317.00
Ry-190
Rz:0

This results into image in focal position of wfs : S_IMG_9071

we then moved the hexapod in tip-tilt. resuklting into:

X:-5.0
Y:-5.45
Z:4.3
Rx:-269
Ry:-148
Rz: 0

This results into frame 9076

From that on we have moved the target in 30mm steps away from the focus. according picture id and distance is:
