Joar Brynnel reports that on 21 February 2019, 4MOST engineering staff from the Georg-August-Universität in Göttingen verified and accepted the support structures for the two low-resolution spectrographs (LRS) at the manufacturer Windelband. In the photo below you can see Heiko Anwand using a laser tracker to verify dimensions with high accuracy and Katja Hauptner holding the retro. The support structures will now be sent for painting. Two of the three supports will then be sent to CRAL for LRS integration activities, and the third structure will be sent to ESO Chile for interface verification on the VISTA telescope.
