Author Affiliations +
Since mid 2002, the complete optical trains of the four 8m Unit Telescopes (UT) are installed and aligned to provide the Very Large Telescope Interferometer (VLTI) with a unique choice of beam combination possibilities [1]. A description of the optical alignment method used and of the final image quality has been given in [2]. We describe in this document the analytical approach used to quantify the geometrical alignment errors not only at the end of the optical train but also at each optical subsystem level.
