The distribution of themean quadrupole strengths along the beamline is shown below:

The variation of the quadrupole strength over these settings is visulaised below:

Clearly the GHADQD32 and GHADQD52 were most played with, however the strength of GHADQD32 is very small, and in both cases the large variation comes from one change of the, value, at the beginning of the beamtime.
Similar analysis for correctors shows that GHADKX1, GHADKY2, GHADKY3 and GHADKY4 were mostly used:

Also GHADMU2 was varied over time, while GHADMU1 was constant:

These changes lead to only negligible variation of the optics. Below the beta function of all optics are overlapped:

The beta functions of target are about 16.39 meters in horizontal plane and 1.3 meters in vertical.
