Last Dec 6, we carried out the survey of the position of additional reference points located in the 1500W building and inside the SQZ-R&D Lab, required for future checks after the installation of the new apparatus inside the Lab.

Tab.1 reports the VRS coordinates obtained for the reference points measured, 1500W-01 to 1500W-05 in the building and 1500W-06 to 1500W-08 inside the Lab.

Fig.1 to 4 show some pictures of the survey.
