At this setting, a survey of both spectrometers was done:
        Left spectrometer:
                        Vertical offset:   -0.48mm        -> yoffset -0.00048 m
                        Pointing:    2.26 mm upstream    -> xoffset+0.001921 m,   zoffset = -0.001190 m
        Right spectrometer:
                        Vertical offset:   -0.040 mm        -> yoffset -0.00004 m
                        Pointing:    3.28 mm downstream    -> xoffset+0.002823 m,   zoffset = +0.001670 m
