This is the lookup table for the distance of each x-ray detector to the target.
See attached foto for explanation.

It is the same values as in 2020: https://elog.gsi.de/esr/E127/36

Detector A (dA) [mm] B (dB) [mm] C (dC) [mm] calculate result [mm]
35° 136.0 (1.0) 20.0 (0.2) 450.0 (0.5) C + B - A 334.0 (?)
90° 76.0 (0.5) 20.0 (0.2) 447.0/2 = 223.5 (1.0) C + B - A 167.5 (?)
145° 165.0 (1.0) 20.0 (0.2) 450.0 (0.5) C + B - A 305.0 (?)

Errors are estimated after measurement, final errorbars have to be double checked!
